Then why do you even respond or debate him? Not being a jerk.. serious question.
Trolling is one thing. What he does is on another level. And the ONLY thing that feeds his ego is trying to prove how smart he is and how dumb everyone else is.
It is entertaining, but the same old routine gets old after awhile.
No one will ever prove him wrong, because in his mind he isnt. And even if he is, he just changes the argument or framework to fit his narrative. He does this over and over and over and the same ones keep trying to argue/debate him. It's like being stuck in quicksand, the more you struggle (argue), the deeper he sucks you in.
