I've stopped giving these people any quarter. The entire ideology is a toxic cult with a physically violent wing which in my opinion should be treated accordingly.
I no longer give it much thought but I have been evolving my opinion generally on how we as a society prioritise resources and attention. My "peaking" journey used to be something like, trans people aren't actually the most marginalised people and we should give attention/priority to others who are more marginalised, such as women in prisons.
My thinking is shifting to something like: "being marginalised/vulnerable" shouldn't be a criterion for priority at all. Society should organise itself around people who are able to fit into it competently, because then it will select for people who are able to do that.
We can't say for years that "vulnerability/marginalisation" gets you sympathy and not expect to have people create spiralling narratives of increasing danger to themselves, trans genocide blah blah, that lead to this kind of openly violent reaction because they've been conditioned to genuinely believe they're in physical danger justifying an even more violent response.
