"It's called counter trolling you moron." Counter-trolling?
AHAHAHAHAHAAAA! That's hilarious! I've never heard that before but its completely ridiculous. The whole point of trolling is to generate negative comments/discussion, period. Doesn't matter what anyone says in response or how logical the retort may be. If it gets replies and pisses people off, the troll has succeeded. To engage them in any form ie counter-trolling is simply playing into their hands. The only way to deal with them, for your own happiness, is to ignore them completely and do Not respond.
