Many individual acts over time can be worse than a single instance of violence that affects many, you realise?
I also very much disbelieve that they constitute any of the left, given that the left largely won't talk to them or acknowledge the validity of their ideas, and they tend to wind up making deals with right-wing anti-feminist (even anti-cisgender-woman) organisations to push their agenda.
Calling yourself a "feminist" doesn't make you one, especially when you stomp on other women's hard-earned rights and privileges in order to pursue your goal of burying "men".
Find me a TERF who openly supports Black Lives Matter and spends a bunch of time advocating for women's rights other than the oppression of trans women, and I'll eat my hat.
EDIT: On the other hand, Black Lives Matter groups by and large support trans folk, at least in words. Black Lives Matter UK: "All forms of oppression are interrelated, you cannot be for Black lives if you do not emphatically support the cause for Black queer lives, Black trans lives [and] the lives of Black women." - and this demo: https://www.theguardian.com/us-news/2020/jun/15/black-trans-... - and this trans person who cofounded a part of BLM: https://en.wikipedia.org/wiki/Elle_Hearns
