These narcissistic tactics they used their whole lives just don't work anymore.  He is literally demanding control over our experience of reality. Only he can tell us what to believe. We aren't allowed to investigate and think for ourselves.  If you try to think then you are insane (gaslighting, slander, threats of social isolation).  You have to destroy your conscience to become like this! He is the crazy one that is projecting at everyone he feels threatened by.  He looks like an animal backed into a corner to me.  He was getting called out in the comments pretty hard.
