That's a pretty generous and kind way to say "became a far-right lunatic regurgitating the same talking points you see from AfD politicians". I don't know what the hell happened to that guy. But he clearly went off the deep end.
Very generous indeed.
I read his substack, he seems to be critical of the US security state and not inline with alt-right principles at all
But in reality he had already done some fairly vile things by then already, e.g.:
* Defending murderous Neo Nazis (not vile in itself, they need lawyers too) while calling their victims “odious and repugnant”.
* Running escort websites and producing cinematic masterpieces such as “Piss Boys in Love”, both with the involvement of his then-boyfriend and later husband David Miranda, under circumstances that seem rather exploitative of the Brazilians involved.
Funny to see someone who seems to be on the left engaging in “kink-shaming.” Glenn has the right to a personal sexual life, including whatever exotic sexual proclivities he may have. Frankly, the film you mentioned sounds pretty tame for gay porn.
