If some is named Charles and you persist on calling them Chuck because you think that Charles is too pretentious, that’s still just rudeness and disregard for the humanity of the person who wants to be addressed as Charles. Imagining that self-identification is a political act rather than an entirely personal one also disregards the intrinsic individuality of the human in question. Hey, isn’t Peterson the king of individuality? Oh, I guess only when that meshes with his political agenda.
