It's one thing to call out instances for tolerating outright bigotry and explicit racial blasts; and individual instances should use the power of mutes, blocks, and even reports to mitigate these threats of harassment and intimidation.
It's something quite another, however, to give absolute power to a clique of admins whose definition of racist actions and behaviors is so fungible & flexible that it can morph into "Anything we don't like is racist, and we represent ALL Black folk in doing so."
