I'll say that I think social ideology of any shape or form, for all intensive purposes serves as a religion. It could be nihilism, communism, objectivism or feminism. If it informs their moral beliefs then it's doing the same thing as religion. Atheism is not a social ideology though. Though it does have cult figures with cult followings. So I'll say "practicing" atheists with doctrines are indeed religious. My religious beliefs could be described as Anarcho-Humanism, but I don't think anybody else would describe themselves as that.
