“Think of the most egregious rhetoric of your least favorite public figure or political commentator, and you can probably induce a quick flash of revulsion in yourself without much effort. George Orwell infamously claimed that the bourgeois think that “the lower classes smell”; he was implying that for all the highfalutin debate and reasoning about political theory, one of the most difficult hurdles to achieving real social equality is that the middle and upper classes are slightly disgusted by the working classes. The upshot is that in addition to its focus on the slime and filth of the physical world, disgust involves itself in more abstract matters as well. When it comes to rival groups or political opponents, actual odor is usually not the source of the offense, however. Rather, it is the very ideology and value system of those whom one is set against that can come to be deeply disgusting. In these cases, it is not unusual for disgust to take on a moral valence.”
