The bipolar certainly doesn't help matters, but it's not the only underlying problem. Even without the swings, on any given day he’s incapable of self-reflection, incapable of admitting being wrong, incapable of taking no for an answer, incapable of maintaining friendships and relationships. He thinks he’s too smart for an education and too smart to have ever read a book. He thinks he can speak on behalf of Jesus and start a Sunday school without having read any of the Bible. He thinks he’s above being cancelled for saying the most heinous things. He thinks he’s an unparalleled genius who can do no wrong, and when someone gets in his way or pushes back on any of this, even gently, he turns on them completely.
And up until the Adidas moment, society has rewarded him and reinforced his behavior every step of the way, so of course he’s still doubling down.
