OP, I'm sorry for some of the responses you're getting here. You're not in the wrong, and white feminism does have more to do. I think the interesting issue is what precisely, and that's worth exploring, I'll set up another thread so as not to detail this one.
I think part of the issue is shame. It's shameful for white feminists to think they have more work to do still on race, when already focused on fighting patriarchy, and to some extent, class. But that's for individuals to address. For anyone wanting more info, the chapter in Reni Eddo-Lodge's book on white feminism is valuable. I don't agree with all of it, but an eye-opening read.
As for the trans activist community being more supportive of Black women... well, I disagree. It's just another way to centre biological men. It doesn't advance black women, in my opinion. There's been BLM protests, BTLM protests - nothing for BfemaleLM and nor will there be unless as an afterthought now. Breonna Taylor's killers won't be jailed any time soon.
And while I wholeheartedly support the movement BLM and anti-racism, I do not support the actual organisation because I am not a Marxist and when I look at their stated aims beyond ending systemic racism, they don't align with my general beliefs, particularly when the U.K. BLM branch is merrily lying that the Zionists are gagging the British press. I can be anti-racist and support the fundamental concept that BLM, without supporting BLM the organisation.
