Oh yeah, this is gonna produce a productive discussion.
Can we all just agree everyone has some natural inclination to favor their own group and to think in stereotypes? But, we also have a capacity/responsibility to check our natural tenancies. We have gotten better across time, but we still have more work to do.
At a societal level, given that whites are the majority and generally of higher social status, nonwhites bear the burden of racism and whites are largely immune outside of relatively isolated cases. White racism is a much bigger issue than the other way around (Sort of the way we talk about radical Islamic terrorism more than other radical religious terrorism). But at an individual level, racist actions are equally despicable regardless of the color of the perpetrator/victim.
