Remember Black Face is a specific thing, not just white people putting dark paint on their face, and the most famous person who did it was jewish. It's all just racism driving these people to criticize white people for doing anything. Their criticism will just get more and more granular until they just decide possessing white skin is the real crime. Pointing out these things is a waste of time because it misses the point. The point is to attack white people, not to end racism. Just remember that.
