The instance seems to be mostly right wing trolls. I know defederating is unpopular but I don't think much is to be lost in this case and it can save the mods some headaches.

I mean, there are indeed issues with the BLM movement. And this "possibly leading to radicalization" is much better than lack of critique.
Say, cultural appropriation is suddenly fine when it's black people doing it. (Talking about Cleopatra in that show, the show itself is not important, just that the "politically correct" approach to it differs.)
Or people who think that BLM is more important than actual ethnic cleansing happening in parts of the planet far away from BLM.
Of course, these issues are inherited from general ignorance and indifference to suffering of others combined with trends of virtue signaling. Same happens in many areas not connected to racism.

Nope.
I don't think this is a satisfactory answer.
Anyway, what I said can be shortened to "everybody who is looking sees you as a hypocrite when you are doing this kind of activism which costs nothing".
