Are we talking about trigger words, or words which carry a lot of personal baggage? A trigger, in psychological terms is
this:
A trigger is something that sets off a memory tape or flashback transporting the person back to the event of her/his original trauma. Triggers are very personal; different things trigger different people. The survivor may begin to avoid situations and stimuli that she/he thinks triggered the flashback.
Using the term "spiritual" may have a lot of history for the person, but unless it was something that came from a place of actual past trauma, what we are talking about instead is words that are laden with connotations, both positive and negative. A trigger on the other hand will cause the person to experience the trauma. Or an event, or a sign, or any other number to things can cause a trigger response.
As a personal example,I drove down a country road the other week which I had not driven in 40 years. But as I approached the spot where I saw that Y in the road and that telephone pole right there where is was those many years ago, it triggered a physical, emotional, psychological, and even spiritual response in me that literally teleported me back into my body when I rolled my car on the spot I was at 2 AM 40 years ago. In this case, seeing that particular telephone pole and Y in the road was a trigger. I had come close to being killed in that accident.
So, if someone is claiming a particular word is a trigger to them, I would ask if they suffered a traumatic experience that is associated with that word. If not, then it's really not a trigger word. Triggers are about traumatic experiences, like a rape, a violent incident, etc.
