Well this is a refreshing place to be. I am an atheist and always have been. My belief is simple. Everyone has the right to believe in whatever they want, just be respectful to others, and do them no harm. I think the world would be a much more peaceful place if it were full of only atheists. Maybe then we could all get along.
I don’t know if atheism is the “silver bullet” we might want it to be — there are (unfortunately) plenty of intolerant and/or bigoted atheists. And we should consider the fact that we’d also probably all get along just fine if everyone was Christian (and acted like Christians are supposed to act). That’s why I tend to concentrate on encouraging people to develop their personal morality, regardless of the religious conclusions they’ve reached.
