Your assertion is false. There are atheist creationists (usually weird liberal nutters though -- I've known some of these), and there are also atheists who subscribe to other scientific theories of speciation besides evolution. I'd say you missed a spot with that brush you are painting with. Try again.
Nonsense. If they believe in God they are not atheists. Your assertion proves nothing except your willingness to say anything, no matter how ridiculous to advance your agenda.
Most of them are in the nut house. Split personality.
