I’d agree that racism and sexism are separate from religion and I didn’t intend to suggest that religion is the source of racism or sexism. It runs much deeper than that with sexism and racism being expressed in different ways by both religious and non-religious alike. That said, where and when I grew up they were all intertwined with and reinforced by religion. So when I threw off the yoke of religion it was easier, for me at least, to recognize the many small and large injustices being committed by me those around me because that was our “culture”.
