Like I said, that comment was by no means exclusively negative and I don't recall where I read the more critical take, but it might have been one of the other (many!) posts about Carlin on r/askhistorians.
Yeah I've read a lot of the more critical takes in r/askhistorians. They don't seem overly bad in broad strokes to me at least. And I think some of the critics may overstate their conclusions, even if I agree with their analysis.
But even with that background knowledge, I think your claim is far too strong.
