Schiff is a psychopath. All your interaction with him is not with the actual human, but the psychopath personality He presents. His true soul underneath is a whithering disgusting destroyed scared insecure feckless aborted fetus. Like all psychopaths, when things don't go their way, they have no normal out for their emotions; they seethe and rage, like the children they are, quietly, privately, inwardly. Their entire existence is this struggle between who they are and who they feel the need to be.
At some point in his life, something went very VERY wrong, and that's when his head split in two. This is their ultimate weakness, they know it, and they hide it very well. No other insult, namecalling, or anything else can hurt them, and that's why they are so abnormal, successful, and dangerous.
I know all of this because I have a "family" (no blood) member who is EXACTLY like him. As yet I have found no singular cure or effective way to combat such a thing, although I do have some ways with dubious success.
His "supporters" are people who realize and believe the façade they present, and/or people who have been so psychologically tormented by them as to be forced to submit.
He is part of this vile class of human being, and I can't understate the dangers that come with them.
