Do atheists make good conservatives?
STUPID QUESTION. There are, no doubt, atheists who are good conservatives. However, there is nothing about atheism that makes them good conservatives.
Would you like to re-phrase?
I leave open the possiblility that you are just trying to stir up trouble. You'll have to try harder than that.
Likewise, there are plenty of religious folks who are not what one would consider conservatives either. Being religious doesn't make you a conservative any more than being atheist makes you a Liberal. They are not one in the same in either case.
