You should only try to do that if you actively want to clear up misinformation for other people at the same time. If you do that, you should also be baiting them into making a fool of themselves when they do respond. If they’re a less experienced or less dedicated troll, they’ll hang themselves on the noose you give them. This will not work if they’re actually good at it or if you are actually bad at it. Learning to judge what sort of person you’re talking to is hard, so if you’re not sure, just ask them to clarify what they said in a leading way.
It’s not about debating them. It’s about humiliating them and then walking away before they have a chance to respond.
