European here, who has clocked up about 3.5 years of living in New England: in cosmopolitan areas, I didn't see much racism against what I might call "melting pot" ethnicities although I heard of some, but I often saw and heard of racism by middle-class Americans against American blacks, including by white fellow students of a black Yale undergraduate. I think that racism in the US is very much a two-lane thing.
