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.
Eh, you assume that it will end his career. It won't. So it's basically a win-win. He showed the id of the ruling class, while also gaining credibility with the ultra-left crazies, which he could leverage to persuade them of something actually good.
