As long as people rise to the stupidity bait, he will keep posting absurd lies to get responses. He probably needs to go away, but not responding to him removes his reason for trolling. You can humiliate him, prove him wrong a million times, and he will come back with some form of "the shitgibbon rules!". He is so ignorant (the part that is not just his act) that he doesn't even understand that everyone is laughing at him.
The only counter-trolling would involve things like "T**** has a deformed dick", but that would just result in more lies about biden. His mouth is never closed, for he needs it to draw his breath, a family characteristic. He would still be jerking off to Melania pictures if he had that ability, which he obviously does not.
