Well, i live in the States, and i can say that all but a handful of atheists were actually anti-christians.

I say this from a point of view of growing up christian, then hating christianity, then learning many other religions and philosophies.

And, what i notice when talking to so many atheists is that they didn't leave christianity for another philosophy, they are just anti-christianity. There are no beliefs there, just anti-beliefs.
