I took a quick glance and it looks like it's because they supported letting a guy who is openly AGP show up at a conference in drag to talk about how he accepts it as a fetish as some kind of contrarian counterpoint to "true trans".

And like...IDK how to feel about that. He's still parading his fetish in public and making other people unwilling participants of it. Just because he's admits it's pretend doesn't make it not creepy and coercive. He's trying to do some pick-me shit while still getting off illicitly.

The point is that fetishes shouldn't leave the bedroom/place of mutual consent, not that they're okay if you admit you're merely a perv but not fully delusional.
