No, that is just one of many examples of how it can happen (and in your case, in both directions, because the name things have in politics doesn't need to match the reality).

Therapists and doctors have to guarantee to their patients that no beans will be spilled just to get what they need to do their jobs.

Whistleblowers need to know their names won't get shared to be willing to blow their whistles.

Filibusters, in the political rather than military context.

That's just off the top of my head.

Society needs a general a priori agreement about what's ok and what's not. If people get to make up the rules on the spot then obviously you will just get into this kind of conflict. (This includes "you hurt my feelings".)

I'm all for banning threats and other speech that's illegal. But once a line is drawn it's in everybody's interest to defend it in either direction. Remember that everything you demand to be banned can be used against your cause at a later point. Similar with every accusation you want to be able to utter.
