I think, worryingly, that he believes that if he screams "BUT IM A GUUUUUUUURL" long and loud enough it will inure him against repercussion and suspicion, more so than honestly believing women are blameless. I think he sees rough waters on the horizon for some of the shit he's pulled and he's shielding himself. I also think the brain tumor talk is part of the same ploy.
This reads as smart, at least insofar as realizing society (especially Canadian society) is in such a place that an ill trans woman will not be questioned on much by the general public, at least not publicly, which is all he cares about, until you realize how transparent he is, and the fact that he can't (or won't) stop poking the bear even as it continues to wake up with its stomach growling. He's going to push the wrong person too far. It's just a matter of time and fortune that what he ultimately does isn't harmful toward someone too vulnerable.
I'm not kidding at all when I check this thread every so often with hopes of posts with news stories stating that he was beaten or killed.
