Sometimes to be a Black person who organises around anti-racism and other -isms with non-black POC means that you have to prove through your labour and through how ‘radical’ you are that you are worthy of being part of the POC group.
Black people are assumed to be radicalised, to have a radical history and to be badarses (not to mention, are apparently not worth caring about as a person)—so when one isn’t ‘as radical’ or radicalised or misspeaks — then a hundred bricks come down.
This has been my experience and I have interpreted it as happening to other Black folks too. It’s mainly perpetuated by really controlling non-black POC.
