Have you noticed how the curtain call works? I have been doing some thought on it and noticed analogies.
Just call the name and the troll appears. The reactions come as reflex actions and not as considered responses much like a serpent strikes at something waving at its nose. No thought, just strike, hurling the venom supplied whatever it may be. It is always the same, just as in this recent case, no deviation, one hundred percent same tone strike.
I call this disorder IDD, Intention Deficit Disorder.
It is marked by the reptilian inability to express anything pleasant or friendly as those traits are bred out of even an understanding. The hapless "victim" can only respond with taught or predetermined venom, in a predicted sequence, mantras first, projection of the "victim's" own weaknesses, sarcasm, personal attack, and finally just babbling towards the end when the venom doesn't take. They are not even aware of the agenda of their masters, to disrupt, to chase away the innocent, to weaken support of things good.
And once their usefulness is over, their masters discard them like a snakeskin.
