A title of a politically conservative or an atheist is merely giving a name to a belief or beliefs. The term atheist means only a person with no god belief. You can have any other views you want or need. Comparing atheism and political conservatism is like comparing oranges and apples.

Now adding religious conservatism to the mix is merely adding a bell to a sheep.

I would say yes but I also think there is a shift going on right now. It seems a hard divide is forming and the preasure to choose sides seems to be building. Someone might consider themselves more conservative but find the far right too distasteful and rigid. It's also possible to fall off the scale all together, just be independant and progressive... not exactly liberal but not quite conservative either.

The spectrum is broad, and there is always more gray than black or white. Would any sane person lump the following atheists into a single political philosophy? Milo Yiannopoulos, George Will, Jesse Ventura, Penn Gillette, Charles Krauthammer, Sam Harris and Bill Maher? Atheism is not equivalent to a political statement.

I say no. Their team is centered around religion, that's the case for conservatives in most countries even where the religion is not Christianity. You CAN however believe in an unregulated economy, a strong military, closed borders, etc etc and still be an atheist. I really hope this happens to the republican party someday. We'd be much better off.

Is it possible to be an atheist and to be politically conservative ? I am quite utre you would have nto define what you mean by "Conservative.
In so far as I am frugal both with my funds and expect the government to be careful as well, yes
In so far as I believe society functions best when all citizens are able to participate and function to the best of their ability, Yes.
In so far as I feel it is good to conserve and protect our environment, yes as well.
And politically as far as I favor the concept of "Promouvoir la liberté, l'égalité, la fraternité et l'opportunité pour tous, oui, ça aussi.
Also politically, as far as government functioning best at the most local level possible being best although in a nation of fifty different states, and some 3,100 (+) County level governments many functions must be managed on a national level, yes as well.
I think all I cited are considered Conservative , at least in my mind, and none are based on being an atheist.
So to get a straight answer you ought to define you terms.

I consider myself to be a fiscal conservative and social liberal. But hey, I'm pretty much the opposite of every Republican out there when it comes to spending. I think Spending on the military needs to be cut by at least 50%, I think health insurance should be outlawed, I think the healthcare industry should be forced back into non-profit status, I think we need to spend money on infrastructure, and I think we need to re-implement the tiered tax system we had in the 1950s.

Bear in mind that the label "conservative" has been hi-jacked by regressives who realize their return to the 1850s can not happen under that banner so they have to hi-jack another route.

I think it's possible, problem is that the conservative party as we know it has been totally high jacked by evangelicals. To pander to their base the overwhelming majority of Republican politicians structure their platforms and policy based on what they consider religious moral codes that most nonbelievers find lacking in logic or reason. In my opinion these labels are divisive and antiquated. Clinging to this religious dogma has alienated most atheist and agnostics from the conservative party. Republicans used to be about fiscal responsibility and limited government, sadly they have let their rigid religious intolerance get in the way of making sound decisions for the betterment of the society as a whole. Personally I think both sides are crooked and have issues lol.

Apparently, although it's less likely due to liberals typically being more flexible, and accepting of diversity.

Scientific Proof: Liberals Are Smarter Than Conservatives [wp.me]

For the most part I agree that we see more flexibility of thought among liberals, who are less beholden to tradition and rigid thinking, so it seems easier for liberals to let go of religion — but there are some conservatives on this site who are atheists, too, so there are no absolutes in this regard.

I'm not sure how a conservative would even vote, considering that the Republican Party increases the debt and deficit far more than the Democratic Party.
