I don't think he knows what reality is, which to me is a big indicator of insanity

You might say! A key to assessing sanity is "reality testing". ✓
Sir #TrumpVIrus of the #Brainspurs invents reality, and then tests limits.

I don't think he cares. He says stuff purely to justify what he's going to do, not because it's real.

He speaks only to his clan in a language only they understand. Asserting that he has made logical and factual errors is not just pointless, it is actually wrong. Like saying, "Hey, that guy's statement in Mongolian transliterates into nonsense." If you are not MAGA you don't know what he said.
