Thank you, Nchewi. Trolls: a person who intentionally antagonizes others online by posting inflammatory, irrelevant, or offensive comments or other disruptive content.
My use of trolls was directed at those who commented, irrelevantly, that she should have stayed in her marriage despite her desire to leave because she would regret wasting 30 years. To me, that is a type of troll, which is a common term defined in many dictionaries.
I was not calling any one a troll like this: In later Scandinavian folklore, trolls became beings in their own right, where they live far from human habitation, are not Christianized, and are considered dangerous to human beings. Depending on the source, their appearance varies greatly; trolls may be ugly and slow-witted, or look and behave exactly like human beings, with no particularly grotesque characteristic about them.
No I was using it in the pejorative sense: expressing disapproval, or suggesting that something is not good or is of no importance.
