Like there are no bigots in NH. When I lived in Central NH I had a long hair and almost got run out of town for being a "fucking long haired hippie"
Naturally that's just the most extreme example; far more commonplace was casual ignorant small-talk generalizing about "the blacks"/"the coloreds"/"the hispanics" in gas stations/convenience stores/the barber/etc. And the soft bigotry of low expectations absolutely permeated an area where people could and did go months, years without seeing a nonwhite individual in person.
You don't have to think I am funny any more than either one of us thought the idiot with the car was funny, but the purposeful, obvious misunderstanding of hate-speak accompanied by finger-pointing and laughter is a valid method of calling out idiots. And I think we can agree that the dude with the car was an idiot.
