I think he may not know. His most used source throughout this discussion is the U.S. army psychiatry report. There's no indication that he's read any of the literature that's. You know. Not written by army staff. In the forties.

(Thanks! Misery shared is misery halved. Anyway, I got to call him out on his lack of critical distance from his sources and his icky gross racist nonsense in the review I wrote so. That was nice!)
