It's beyond that. It's clearly a symptom of a sort of insanity.
I don't like Trump but I can manage to visit news websites with photos of him. This is true of sane people.
But Trump cannot accommodate Buttigieg on Fox or McCain's name on a ship. That is downright extraordinary. Not in the range of normalcy.
Same as all of his behaviour, which is always all about himself. I don't think he knows what normal is. He can't even imitate it.
He is an obvious case of a person whose best defence is the insanity one. It's a shame he is president rather than, say, a murderer where they know what to do.
