Actually, I was raised an atheist, more or less. Thing is, society doesn't exist in a vacuum, neither does history. Our history and morality were massively influenced by religion. Again, strawmaning about me saying that somehow religion has the monopoly on virtue and morality, which I didn't. Arguing that in the vacuum religion would be unecessary to our current views on morality is turning back to reality, but, I see that morality has no basis in reality, aside from subjectivism. The Aztecs were perfectly moral in their skull piles. But sure. Western civilization and history don't matter. All that matter is that vacuum you defend that morality exists and that its path is the same as ours, somehow.
