Now, maybe I just missed something, but I don’t remember reading David Chapman mentioning Less Wrong specifically. So I don’t understand his opinions per se to be attacks against rationality as defined by LW.

I imagine (perhaps incorrectly) that he would agree with some parts of LW common knowledge

He just seems to insist that the true meaning of “rationality” is the Vulcan rationality
Your understanding seems to match what he says in these tweets:
Important: by “rationalists,” I do NOT primarily mean the LW-derived community. I’m pointing to a whole history going back to the Ancient Greeks, and whose most prototypical example is early-20th-century logical positivism.
I think that much of the best work of the LW-derived community is “meta-rational” as I define that. The book is supposed to explain why that is a good thing.
