And it seems that black americans protect white people when us Asians another minority are attacking white people as much as they are.

It's simple you see. What is perceived to be a smaller race, gets the most dehumanization of all races. White people are obsessed with the phallic member as a symbol in their buildings and skyscrapers, they think bigger is better. So the smaller you are the more dehumanized of value of human life you are. They want to push around the smaller guy while preserving the bigger guy. Hence why psychologically they're more protective of black people than Asians.
