Trigger is either an action or an object. It
may refer to
two things:
(1) An object in a firearm, commonly referred to as “the trigger”, that, when pressure is applied to it, causes the firearm to discharged, by means of a mechanism.
(2) An act or event that causes a reaction of some sort.
HOWEVER.
Trigger is NOT a word that can describe a negative reaction to a piece of literature, an
opinion, a fact, or an opposing statement. The correct word for that is “overreacting”, or a combination of
words, such as “an overly sensitive person who doesn’t like to hear opposing options”.
Don’t like it? Too bad. The word “trigger”, alongside many other
words, is not yours to be manipulated.
