This is not at all true. For example, in new age communities, "triggered" is used very frequently to mean that someone's personal ego wires have been tripped -- and in fact the reason the word is used is because it's understood that "being triggered" is not that big a deal, it's part of being human, and one may get very upset in the moment but with perspective one sees it's fine.

This is obviously very different from the PTSD-only meaning you are talking about, but I would bet that the new age version of the word has been in use for much longer and by many more people.

So ... I sense some presumption and lack of exposure here, is all I am saying.
