He's apparently always been an asshole from the many accounts that have come out over the years
IMO the more recent public switch of tone is either too many drugs have scrambled his brain or much more likely someone very powerful has something very bad on him and is using it as a marionette cross-brace to further extremism.
I recommand reading threads.net account of one of his child (she activated federation). She really exposed how he has always been liked that and he is just good at manipulating his public face.
from what i understand the had a personal pr department for his own image, then he got too full of himself because they did too good of a job making people like him. dumb ass narcissist assumed it was all him and fired the pr team. now he's just himself and everyone hates that.
Maybe he got the brain worms. I’m starting to become more and more concerned about these brain worms. It’s like the adult version of cartoon quicksand. Should I be worried about brain worms?
