* government officials (as you say), members of federal agencies, civil servants etc.
* journalists
* healthcare workers and emergency services personnel
* educators
There may have been more on my list, but it doesn't come to mind at the moment.
All of these are places where a mindset that glorifies or justifies political violence and death seems like it would be an impediment to actually doing the job properly, which is the only thing that would make me accept "cancel culture". Others may be morally unjustified in "crossing the line", but should not lose their jobs for it.
For me, the line is drawn where anyone proposes that anything a person said justifies or excuses killing someone. The "stochastic terrorism" argument is especially insidious: it attempts to launder "speech" into "violence" (and thus justify "an eye for an eye" etc.) by hand-waving at some vague notion of, basically, extremely non-imminent incitement. The idea is that convincing a wide audience of people to have a more negative impression of a group stochastically increases the number of members of that group that will die to violence. But none of the dots are ever actually connected in this argument; and taken seriously and applied even-handedly, it would make basically any form of political discourse impossible.
Initially, I thought Matthew Dowd's comments (I had very little exposure to them) didn't fall into that category — that they were simply made in incredibly bad taste. But I looked up some more of the transcript and, yeah, I can't excuse that. Certainly he wasn't as aggressive about it as, say, some Bluesky users. But part of it does fundamentally boil down to making the "fuck around and find out" argument, and "finding out" is just not supposed to involve being shot and killed.
This is fundamental for me; see e.g. https://www.lesswrong.com/posts/svuBpoSduzhYjFPrA/elements-o... .
