Proud atheist, and I'll stand on it.
I grew up hardcore Baptist-- that's the predominant religion amongst Black folk in South Central LA.
I used to believe atheists were Devil Worshippers
Then, I learned a lot more, asked a whole lot of questions that couldn't be answered, and fell out of the religion. I used to debate religion, on both sides. These days, I don't care what people believe, as long as they leave me the fukk out of it and are not actively harming anyone else, like Muslims do to gays in the middle east.
Basically, religion doesn't concern me and I don't think about it in my day-to-day life anymore.
I will agree that there is some utility in the community aspect of religion. People can come together for a good cause based on their belief system, and overall, I think that's a societal good. The Ten Commandments are generally good pieces of advice (with a few exceptions) and I don't see any problem with, say, a Christian living a charitable life seeking peace amongst their community and doing good deeds.
