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.
I guess I see your point but I also watched Fox News/Christians get up in arms (years ago) when a seasoned religious scholar (Reza Aslan) wrote a text on Jesus because he was not Christian. Ultimately it’s how much the individual author knows, not the group they associate with, that determines if somebody can write with authority on a subject.
Anybody can write about Richard Dawkins in any context so long as they actually know what they’re talking about. Hell Playboy was a major literary and political/social thought magazine for decades.
