again: i'm the leftist. leftists reject religion; it's really the fundamental aspect of being a leftist. if you don't reject religion, you're not a leftist.
religion correlates on the right with authoritarianism, capitalism, hierarchy, heteropatriarchy and class division. that's what religion is. you can't separate it from these things, and it's the reason capitalism is so reliant on it to enforce itself.
atheism correlates with anti-authoritarianism, communism, egalitarianism, feminism and democracy. that's the point of being an atheist. and, you can't get to ideas like democracy or feminism without tearing down religion, first.
so, i'm perfectly happy to argue with you if you want to stand up for religion, but i'm always doing it from the left, and you're always defending yourself from the right - whether your spectrum is restricted or not.
