"Concern troll: a person who disingenuously expresses concern about an issue with the intention of undermining or derailing genuine discussion."

Yep, that's name calling. It's also poisonous to the discussion. It's not "criticizing behavior" when I wasn't doing it.

More importantly, it makes for boring reading. You can see how unproductive the conversation became.

But whatever. Just have thick skin, right? We can't simply expect people to be civil.
