Richard Dawkins recently explained that he self-identifies as a cultural christian. He doesn’t believe in Deus, but he enjoys many christian traditions, including carols and hymns. This particular article is written from a Christian perspective, which I do not personally agree with, but it correctly interprets that Dawkins’ cultural christianity seems to be a dogwhistle for whiteness. Many atheists like Dawkins are cultural christians, in ways that subtly reinforce white supremacist narratives.
Richard Dawkins sure is a religious atheist. Religion is about a lot more than just theism. It can be a system of spiritual, philosophical, cultural, and/or moral beliefs. There are plenty of religions that have little to nothing to do with gods. For example, Buddhism. There are plenty of Buddhist atheists.
