Yep, they've ruined the word.  When I use it, I mean that I have a weakness that means that certain words and events will anger or distress me.  So if I freak out a little at something, and the person is wondering why, I might explain how it's personally triggering to me.  That means that what they said isn't actually offensive or wrong; it's just that I personally have a reaction to it.  In other words, I am explaining and apologising for my overreaction, not rationalising it as SJWs do.
