Part of me thinks his outrageous comments are intentional as he now has billions of dollars & unchecked power. So he has it all: money & power. He can say & do whatever he wants with impunity. No one has the guts to stop or restrain him & he knows it.
That is the very reason someone needs to just read him for filth, cuss him out & walk away. Nothing else has any effect so might as well let that stress loose on his ignorant behind.
That’s the thing, tho: anyone who dares to oppose him/call him out on his lies or says/writes something he doesn’t like is retaliated against. That retaliation is intentionally made public to instill fear and passivity in others. Unfortunately, this is an A+ strategy for authoritarians & fascists.
