As a guy that has a white step mother, yes she can be racist, the same as Rev Wright can be a racist. My mixed brother was called the N_word as a baby to my step mom's face and she called them one right back. They in my opinion are both in the wrong, but one wrong doesn't right another. I beleive people to be primitive beings in that we all have blood in gerneral runing though our bodies, 98% salinity, yet we impune each other with radical differences of opinion. Human judgement is imperfect because most if the time it can't be impartial.
