This goes pretty deep in English. I'd argue that the semantic intention behind the colloquial usage of "vulgar" is nearly inseparable from the "class distinction" baggage it carries. Consider these common synonyms and their etymologies: - Rude: "coarse, rough, unfinished, unlearned" (https://www.etymonline.com/word/rude#etymonline_v_16610 https://www.etymonline.com/word/rude#etymonline_v_16610) - Mean: "shared by all, common, general" (https://www.etymonline.com/word/mean#etymonline_v_12495 https://www.etymonline.com/word/mean#etymonline_v_12495) And even synonyms like obscene, indecent, or disgusting, which don't evoke this distinction directly, still almost always ultimately rely on separating things based on what is "good" and "clean" according to class distinctions.
