Christian's still burn witches in some nations. What you don't understand is he link between poverty and religious extremism. There are Christian's doong that shit still.
Yup and Atheist extremists end up like Marx and Hitler.
There is no such thing as an atheist extremist. Hitler used Christisnity to influence Germans. Communists setup their leaders as gods. Neither is an example of atheism.
Communism is not based on atheism. Communism requires the people not to listen to so other higher authority is the issue. It doesn't like the competition. It is almost a religion.
Explain how it is a basis o socialism. Why is it more fundamental than say the elimination of private property rights? How is worshiping the leader/state a form of atheism?
Because without atheism the state cannot impose itself as the supreme authority. Theists in all its forms will always see the state as an inferior form of authority.
Replacing one god for another is not atheism. Either way it doesnt make atheism the basis of socialism so much as the elimination of private property rights is the basis for socialism.
TBH I think most Christian's and Muslims do not consider their God a highest authority. It seems most people just do it because everyone else is doing it. Only extremists are believers
You should begin to read both the Bible and the Qur'an if you want to have a credible opinion on them both and have meaningful discussion. It's kinda of obvious you haven't.
