“…white people have prejudices about people of color because American culture has normalized whiteness, but the fact that people of color act “differently” further entrenches the “obvious correctness” of a white cultural norm.”

I call BS. You say that I have a bias that I am not aware of just because I am white. That in itself is prejudiced and biased. You assume that all white people feel and think the same. I will not fall into the trap of feeling guilty just because I happened to be born to white parents. I had nothing to do with the color of your skin, my skin or the skin of anyone around me.
