I'm a relatively new atheist who lives in the middle of the American Bible belt. I'm still in the "phase?" of reading everything I can find on the subject. (I do like Boghossian, Joshua Kelley, Penn Jillette . . . ) I gradually became atheist by a combination of reading scientific literature by Sagan, Hawking, etc., and sitting through church services that sounded increasingly insane. So no, I have no actual community . . . unless you count this forum. My brother is also atheist but we don't discuss it much.
