“Trolls” is actually an old net term from w-a-y back, where people troll threads throwing out inflammatory rhetoric hoping to snag people into a flame war.
Some people get off on that kind of thing.
It’s one thing for a flame war, or argument to naturally progress of a disagreement, but thee are those who go around trying to create it. And it gets tiresome and disruptive.
I'm on one unmoderated group where there are some very educated and intelligent people in flame wars way worse than here. It's hilarious.
