Another thing that seems to fit this pattern that I have seen elsewhere is a Trigger Warning, which is used before people discuss something like rape, discrimination, etc... which can remind people who have experienced those about it, causing some additional trauma from the event.
Has anyone here ever decided not to read something because it had a trigger warning? I can't imagine doing so myself, but that may be the typical mind fallacy.
EDIT: People do use the warnings. Good to know.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
