I agree, you are confused. A white American telling a British American, say one who was naturalized, to go back to Britain because he perceives him as non-American can certainly be called racist. The common use of the term racist isn't only about "race" per se, but about ethnicity, national origin etc...It encompasses it. But like I said, it doesn't pack the same bite. In earlier eras many white Americans were "racist" against Irish (and Italians and Germans etc...)because they weren't WASP. This has morphed into a more diffuse whiteness where even those who were "otherized" such as the Irish have become part of the white establishment. NTL, there are many remnants of this earlier racial hierarchy that sticks with us today. So again, if Trump turned his eye on Cubans or "Cuban Americans" and attacked them like he does other minorities such as Omar, would you continue to defend him? Or another way to ask, what will it take to get you to see what you seem determined not to?
