"so, wait. you would only support the blacks if they have politics you agree with? where's your solidarity?"
listen.
if you think i should support a movement based on identity politics, then i think you're what's wrong with the world.
yes, i will support you based on whether i like your politics or not, and if you think that's disagreeable, then i'll have to disagree with you.
as an anarchist of the left, i support police & prison abolition in it's most extreme and literal sense. however, i don't support "retributive justice" in any context, whatsoever; i think it's barbaric, and i think people arguing for it are barbarians.
and, i don't care about your race, your ethnicity, your religion, your gender or any other sort of identity you'd like to claim for yourself.
