My mother family is mixed of black and native american.
Almost every single time I faced discrimination, was because I was "white", for example open hostility by 100% black people assuming that I was "white" and evil or something, or when I was informed I should not apply for affirmative action because I was too white looking, or many, many times I was called racist as soon people saw a picture of me during some argument or another.
To me it is obvious that further segregation and racism, is not the answer to segregation and racism.
