Eh, I mean, he was always pretty bad, but it does _feel_ like he's gone totally off the deep end. And he wouldn't be the first; notably, plenty of people around his age went _very_ weird around September 11th (you may remember Christopher Hitchens' weird voyage of personal discovery from basically a pacifist to a bloodthirsty war hawk to eventually getting voluntarily waterboarded, for instance; to his credit he did somewhat recant at that point).

I suspect covid, both the stress of the event itself, psychological impact from isolation, and brain damage from the disease, screwed people up more than we give it credit for.
