I think this is a larger extension of the internet problem where accusations are cheap and their impact great.

I find myself qualifying my statements or even not bothering with some ideas in some spaces occasionally because I know it will be construed as some extreme I'm not supporting and after that starts you really can't have a conversation.

You can take my em dash from my cold, dead hands.

Ditto. I’ve been using them for literally decades (because the old Macs made them so easy to type). And with X11 and xkb they’re even easier!

I do worry that some of my comments have been downvoted by kids blindly downvoting anything with an em dash, but at the end of the day I prefer good style (by my lights) to imaginary Internet points.

If you write like AI now then writing differently will be an improvement.
