Also, I've never seen such a tiny percentage of the population get so much attention. I've never seen a poll with atheists comprising any more than 5% of the population. Yes, there are many more who aren't religious, but that does NOT equal atheist.
I would instead look at atheism as part of a greater non-religious community, which would include atheists, agnostics, people with no religion and secular religious people who don't believe in any religious doctrine seriously. Someone who is merely a deist in a very bare sense that they believe in some mystical thing like "the human spirit" or "nature" or "love," is basically an atheist.
Belief in God in that sense, existing or not, is actually pretty inconsequential, right? That debate is basically an irrelevant philosophical argument. There's no reason to believe in God certainly, but it's an attractive, comforting idea for some people.
The real step off the deep end with religion is when you start saying, God told me to do XYZ. That's the problem with religion anyway in the eyes of atheists. It's not so much the religion itself, it's the irrational, harmful behavior caused by magical thinking which predicates religious belief.
