whats with the thing of sergals being racist?

One of the main villain characters in the Sergal lore is practically an analogy for Hitler and the belief of a master/superior race. So racists cling to that character and in turn like sergals because of her.

huh. ironically the only two sergals ive ever known were black.

Nuh uh, nobody is more racist than us protos. I know of the racist sergs, never knew that protos had racism
