THAT’S NOT VERY NEIGHBORLY: Mexican audience boos Miss USA. If an American audience booed Miss Mexico, it would be racism.
Well, probably, because the average American is not acutely aware of or vehemently opposed to important elements of the policy of the Mexican government. So racism would be a pretty good default explanation. If Mexican police had just beaten the hell out of a couple of American tourists or something, the explanation would probably be different. Not that the booing isn’t rude and objectionable anyway, but sometimes there’s asymmetry in the motives people would attribute in parallel cases because they’re not actually all that parallel.
