I feel most closely aligned with that thought.I don't think the majority of white people are racist in a hostile, or superior way. If that makes any sense. As in I don't think most white people walk around thinking "I hate black people and I know I'm better than them.
However, I think most white people are racist in a built in prejudice/ignorance fashion. As in, maybe they see a black guy in a hoodie walking down the street in the evening and get nervous, kinda way.
And perhaps more also along with things they may do knowingly or unknowingly (ie, is anyone on your committee not black, is anyone in your photo of *insert event* not black, did you choose anyone of your non white students in class to speak (do you give them a void, do you actually look non whites in the eye when you talk, do you change how you talk/words you uses/etc to nonwhites?, do you say hi to the nonwhites you pass by like you do the whites), also conversation topics and etc...
I've gotten some pretty weird questions from people who must have never had any type of substantial conversation with a black person before.
