They use the white supremacy thing, racism, bigotry story line to scare weak uniformed white people from uniting. They realize that if the white population that represents 75+ percent of the population united and brought along with them even a small percentage of any other demographic it would be the end of them. They use all their power to separate Americans by race and then use their political wins to import as many non whites into the country (who they immediately indoctrinate) to break the white voting block up even further. It’s basically the most racist agenda ever conceived, it is pure evil.
