Or just don't respond to it. I have been in foxy's shoes many times. Unwinding white supremacy, racism and its rhetoric is not any fun for anyone. It is a complicated but repetitive task. And it is a task that isn't your job. Even that had to be explained to me. I wouldn't say "sorry" as I would say "thank you." It is very bodhisattva-like behavior, but it only pays out patience. Much like giving art to publications for free yield "exposure." But there are a lot of us white peoples that are slow learners. We were told we are actually superstars. That we deserve everything no matter what the historical cost. That is really difficult position to get someone out without serious life-altering events. Perhaps imprisoning the entire population for one year that is served by de facto white supremacy can't be done. But it would surely be the fastest.
