Whether or not you've dealt with a troll before doesn't really matter.
You think I've never dealt with people like you? The people who think they are too smart to be trolled are the easiest people to troll. They usually start the arguments with trolls. They reply to ****-posts or butt into other arguments. They start out by trying to prove the troll wrong, instead of supporting their own views. When they realize that they are being trolled or that the troll doesn't care about what they think, they declare proudly that they know they are being trolled. They claim to know what's going on and they know all the reasons behind it. They will ask the troll questions about the troll's life. Abusive family? Neglected? No friends? "You'd never act like this in real life. You're pathetic." They'll go from asking questions to telling the troll what the troll is. "You're autistic." (I've gotten that one a lot.) They tell the troll that they can't be beaten and that they know how to deal with the troll. They're just too smart.
But here's the thing these people never seem to understand: when they replied, they lost. Trolls want to argue. Trolls want to post a lot.
I'm legitimately having fun, and you're now my source of entertainment.
