I used to know a trans woman who advocated for "drop the T". She was an awful person in some other ways as well, but the groups I went to wouldn't do anything because they wanted to be inclusive. It was the paradox of tolerance being played out in realtime, at the cost of anyone who didn't conform to her ideas about sexuality or gender presentation.
If I were the CIA, I would simply let the man nobody likes speak at length at every single activist meeting, making it impossible for them to plan anything, and accusing them of being ableist if they don't allow him in
