TERFs have always sucked terribly, but I feel like recently they've added layers to their maliciousness and ignorance. TERF as a slur, hiding their transphobia behind "gender critical" ideology, the escalating connections between them and conservatives/the alt-right, the idea that being anti-TERF is actually being misogynistic. It's been weird watching the evolution (seems that way from where I stand, anyway) of TERF rhetoric and tactics.
Also, I don't think it's a coincidence that at least 2/3 (did I overlook anyone?) of the people who were banned in this thread are from the UK. The UK certainly doesn't have a special claim on transphobia, but this particular manifestation of it, reactionary and couched in pseudo-feminist language and unfortunately all too influential even in the mainstream, seems very much to be a uniquely UK phenomenon.
