Gould came from a family of Marxist atheists. So his views on the matter were fixed long before he became a scientist.
Evolution is a theory that is religion-neutral. Therefore "evolution is anti-religious" IS a false statement.
When I see that sort of thing, I remember that scene in "Short Circuit" where the doctors explain that Number 5 "doesn't get happy, it doesn't get sad. It just runs programs."
Perhaps we are getting a glimpse of what we are up against. The Anthropomorphism of a school of thought.
So you think you are mind-reader and know Gould's secret motives - whatever
If there is one "pusher" of evolution that is anti-religion then it is a false statement to claim Evolution is not anti-religion. Unless you want to argue the nonsensical position that "theories have no options"
This is simple logic.
