I just realized why I've lost all respect to JB Peterson in the last few years.
He no longer actually debates. So, obviously, if he no longer is speaking to people who actually disagree with him, his critiques cannot possibly affect the oposition or even describe it accurately.
The same thing did happen to Sam Harris. He outright refused to speak to people who disagree with him, and after a few short years, he wondered, why is everyone looking at him as a loon, when he went on his famous rant.
