Does each one speak for all the rest or do they have denominations and schisms as spiritual and religious people do?

This is just another transparent attempt to say that non-belief is a form of belief. Jack, can you tell us why you keep saying this, why you keep starting contentious threads on this subject? You keep asking questions like this while ignoring being told hundreds of times that atheists have nothing in common with each other other than the fact that they don't believe in gods. So . . . if you're not gong to believe what people say on the subject, why do you keep asking the same question over and over?

What is it about atheism that bothers you so much? Why aren't you asking yourself that question?
