Secular Atheist.  I can't explain why, I just am.

I think the number of Conservative Agnostics and Atheist might be higher than you think. I could be wrong but.....

If you think about it, Conservatism for all its asserted Superior Morality...the calls for Prayer in Schools, The Plastering of Christian symbols all over goverment buildings, the crusade against abortion, Same Sex Marriage, sex education etc......is at its very heart, not very Jesus like at all.

Selfishness (or Fuck thy neighbor as I like to call it) is at the very heart of their political philosophy.

Conservatism back in the Goldwaters days reflected this and it really wasn't until Reagan when the decision was made to join forces with the Fallwells and the Moral Majority as a political strategy did you see this shift and explotation of religiosity.

It was a pretty good strategy and trade off from the Conservatives point of view. They gained the support of a large block of people who took thier support to almost religious levels. Either vote Republican or go to hell? That is pretty strong support. It became intertwined with their very religion itself. This is alot to receive and the many people treat their leader like religious people themselves.

For the Conservative they had to give back little $$$$ wise. Being anti-abortion, anti-gay marriage, letting a cross go up here or there costs little to nothing. Conservatives are quite pragmatic in this way. The $$$ they were able to make with the support of the Evagelicals especially the last 10 years has been immense.

If you ask me, the evangelicals are the ones who gave up the most. Jesus is now someone who wants the poor, sick and old to be spat on and called looters and theives in his name no less??

Just because you are Christian doesn't mean you love thy neighbor. There are many atheists who defintely don't and would gladly pretend if they are paid enough in return.

Ah, I'm bored today, why not (puts on troll hat). Sinful though I may be, I feel like tossing a few stones.
1. "Even if atheists, agnostics, and various nonbelievers disagree in the
details (i.e., when sex education should begin) almost all share strong
liberal conclusions (i.e., there should be comprehensive sex education
in public schools)." --This group is defined as not being conservative. They are not defined as having a united set of opinions, and I'm amused that you ascribe to them a nearly (licks lips) religious unity in thought and action. Ahem.
2. Ascribing bullying, group-think characteristics to a majority merely for being a majority leads one to certain conclusions that if, instead, atheists were in charge, little would change. Think about it.
Also, many of the differences between Christians and atheists in beliefs are more easily defined as a difference between collectivist and individualist world views, rather than conservative and liberal. The atheist, already an individualist who has decided to part with the usual way of thinking when it comes to religion, is more likely to support individual rights in sexuality, for example.

@GreekPhysique - Yea you could be right, I am really going off of what I remember. I was a baby Nixons day. "Culture Wars" are very well ochestrated conservative tactics and are highly successful. It puts the Christian in the position of supporting the Righteous Conservative (and all the fucking of thy neighbor that is cleverly obscured and the attention is distracted away from that comes with it) or the Evil Godless Liberal. Divide and conquer. Machiavellian for sure, I don't think it is very Jesus like from what I can tell.

I think the main reason is that conservative social positions (I.E. no abortion, gay marriage, etc.) nearly always have their basis in religious beliefs, with a few pseudo scientific "studies" thrown in for good measure.

As @tendollar4ways - says

"Selfishness (or Fuck thy neighbor as I like to call it) is at the very heart of their political philosophy."

This is exactly how I've come to see conservatism (at least social conservatism.) Conservatism is rooted in mankind's fear of, and concordant hatred for, the unknown. Conservatism is the knee-jerk reaction to seeing something you don't understand and trying to destroy it. It is ignorance and intolerance. It is the tyranny of the majority and in a nation where the uneducated white Christian constitutes the majority Christianity and conservatism go hand-in-hand. Conservatism means to think small, to think selfishly, to think ignorantly. It seeks to preserve the status quo, rejects progressive thinking and assumes the worst about anything different. Religiosity generally encourages the same things. Even when a specific religion starts out with what could be construed as 'liberal' ideas over time the doctrines themselves become the driving force rather than the message behind them and so conservatism is born. Hell, every last conservative today is actually touting the ideas of liberals past.  The difference is that whilst liberals acknowledge the importance of the mind set behind each philosophy and continue to adapt their thinking and ideals based on new information (much akin to the scientific process) conservatives are interested only in the doctrines and how they stand to gain from them personally, selfishly clinging to that which they are familiar and comfortable with, never troubling themselves to consider what life would be like were they born other than what they are (much like the religious mindset.) . Like tendollar said, "selfishness." It all boils down to selfishness.

It's easy to forget that 'conservatism' is not a set of universal values but rather an attitude adopted towards the traditional values of one's cultural parent. A Russian who grew up with communism and seeks to maintain that way of life even when change is in the air could be described as "conservative" despite the two being mutually exclusive in the eyes of many Americans. For this reason conservatism is highly divisive, even amongst conservatives. Two people both identifying as conservative meet but, should they come from divergent cultural backgrounds, they are at each others throats (Christianity VS Islam, for example.)

Conservatism is polarising and discriminatory, taking pride in its devolved approach to life. It is the reactionary cry of those who would sooner screw another over to suit their own ends. In Plato's Cave it is those that beat the man who turns away from the wall to death. It is mankind's most ugly traits given political form.

If a person wants to believe in a Devine reality vs the person  that chooses the free will to not believe that there is a Devine Reality, then so be it. This is an issue that will never cease. Reason being is because most people do not believe that God created the world or mankind. There is the Big Bang Theory, then there are all these other theories about religion and evolution, and the religous context of social conformity and all other issues that encompass the ethical issues of what is right or wrong. First off, some people do not think that a God exists, which mostly is because they feel betrayed or because there is no real logical proof or evidence that God exits. Then they feel that some issues should not be resolved by religion, or they have strong beleifs that their way is right.  My backup is just because we can't see an emotion like love does it not exist, or hate can we not see the hatred actes and events. And now this drama, forget it I am considereding a conversion to a religion that is emphasised on personal experience and logic because the contreversy about ethical delimmas of right and wrong will always be, can't everyone just learn to get along and accept the diversity in each of us?

"Why Aren't More Atheists Conservative?"

I think it's like you said: they may be turned away from conservatism because of "bullying" by politically-invested Christians. I can't think of any ideological reasons why atheists should naturally be opposed to, say, capitalism or naturally support gay marriage (there are some homophobic atheists, no doubt). A disbelief in God does not tie into these things. The only thing I can see atheists by default supporting is the establishment clause of the first amendment.

Christians, and many other religions, on the other hand have ideological reasons for supporting certain stances (e.g. no climate change, no gay marriage), even if they're misappropriating their religious texts in doing so (in fact the irony is that Christianity at its core is economically socialist, though not through force by the government).

Libertarian Christian...

"Why aren't more atheists conservative?"

Probably 90-100% of this is a result of the media being so 'black and white'. Its the same reason more Chrstians are not liberal. It is the same reason why you are using the words liberal and conservative. The reality is that either party are the two sides of the same coin. They both look to government to solve perceived problems by force. Probably the most significant differences lie in what they think the problems are. ( Apparently it is impossible to solve the problems of homelessnes or prostitution without the use of violence. )

I used to consider myself pagan.  I am in no way conservative, but think that there is a reason for what you speak of.  Christians think that anyone who doesn't believe in their God is going to hell and evil.  Would you want to associate with those who think that you are going to hell because you believe something else?

There is this idea in America but especially in Evangelical circles that one should be dependent on no one (I think that phrase pops up in a Pauline epistle of New Testament at least once).  They get to choose what falls in this criteria so for example a soldier and an individual with a disability might both be receiving health insurance from the government but only the latter is scorned.

Of course Jesus did have a lot of things to say about looking after the sick and needy but evangelicalism leans more heavily on the Pauline epistles for its core beliefs.
