If I was trying to troll you, I'd have mostly agreed with your article then made some outlandish accusation or completely incorrect statement. Then I'd defend that while continually moving the goalposts and getting people as invested, amused, and angry as possible.

Simply stating an opinion, by itself, is not trolling no matter how much you may disagree with the comment. If you're open to advice, I suggest that you look at a user's comment history to determine if they're the type of person who trolls others.
