Is he going to persuade someone who does not have TDS to get it? No way. He's way too over the top for that.
But may he persuade some other people with TDS to oppose wokery? And does the fact that he has severe TDS give him more credibility to do that? Yes.
So on net balance, he's a force for the good.
Anyone who jumps to the defense of Sam Harris like this is someone I would consider to be as the kids these days say "looking pretty sus".
