>>4453761It's a very simple former master/slave dynamic. Members of the former master class are threatened by the former slave class and will do anything to put them down, either physically, verbally or mentally. This extends to zero tolerance when it comes to bants.
You see it all the time with japanese/koreans, swedes/finns, russians/east europeans, brits/indians, turks/kurds, etc. For some reason white americans are extremely sensitive to this and will just instantly flip if a "negro" steps out of bounds.
