I'd say that maybe 10% of white people might be hardcore racists.
10% might consciously acknowledge racism and fight it.
and 80% understand that racism exists...they really don't have purposeful hatred in their hearts, but they never think about how racism affects people on a daily basis because TO THEM it doesn't ever really have an impact.
So it's like
Person A: Oh, that Michael Brown situation is crazy.
Person B: Yeah that's fukked up
Person A: So I'll see you Equinox later, right? Trying to break 225 on my squat
Person B: No, I can't. Tracy wants me to join her for Yoga outside at Bryant Park.
Person A: Oh, okay. Later bro.
