People trying to be the quippy cool kid and/or act condescending towards people they view as ideological enemies was an issue on Twitter long before Musk. Arguably, this irony-laden, artificially detached, everything filtered through a snappy one-liner style of commentary (“ooh, that’s not a good look,” “villain origin story,” “being an [x] is a bold choice,” etc.) is a core personality trait of the modern leftist, so in shaking the dominance of those people up a little, Musk may have, if anything, decreased the prevalence of that style of communication.
