I think the most important thing to get across to Trolls is, "Hey! I see you for what you are. But, I still actually see "you." And, I can (and will) accept you, warts, problems, fears, hatreds, hang-ups, phobias, psychoses, perversions, and all.... despite the mask you are presently trying to claim is really YOU."
"But, we are neither one going to get anywhere, if we continue on this present course."
