Unsolicited advice:
You should watch some Christopher Hitchens videos.

There is no reason to be tolerant of intolerant world views, bigots, racists, misogynists etc. .

Go ahead, judge. It is what evolution gave us to survive and make it to the top of the food chain… so to speak.

Atheism is not a belief system.

Argue against the beliefs or position, not against the person.

People argue in order to fixate their own world view… mostly. If you argue against their position their position might change. If you argue against them, their position will fixate.
