When Trump says that he could shoot someone in the middle of Fifth Avenue without losing the support of the MAGA base, Trump is, of course marveling at his own popularity. But he is also admitting his deeply felt disdain for the rubes and marks who have fallen into his hands. Trump’s contempt for his supporters is shared by others in his orbit, including Bannon, who know that they can monetize their lies and scams by fleecing their most loyal backers.
They are counting on their marks to: (1) continue to buy the con and pony up the cash, (2) not realize that they are being lied to and ripped off.
As David Frum has repeatedly noted, victims of scams are often angrier at those who point out the ruse than at the fraudsters themselves.
But as hopeless as it might seem, somebody needs to tell them. (Source)
There's no point in trying to tell them because they're convinced they understand some deep truth that others don't. They sincerely believe they've taken the red pill, not realizing that, in fact. they have taken the blue one.
