I used to use em-dashes online to seem smart but now that internet addicts are defending them in order to be contrarian about AI slop, I'm abandoning them altogether. I have to finally admit that I actually think they're stupid and I don't want tiny differences in the length of a featureless horizontal line to be grammatically significant.

Especially when there's never any context where you can create a minimal pair between two utterances that would give them a different meaning depending on which dash was used. An em-dash is just a stuck up en-dash. I even hate the terms "em-dash" and "en-dash" now, after the typographical snobbery that flooded the culture for about a decade after web fonts got invented and standardized. Frontend developers and web designers started getting big salaries and buying fancy wines and whiskies, so I had to hear the word "Helvetica" 50x a day.
