First and foremost, he is the (very) willing face of this catastrophe, and he deserves whatever scorn he receives. So yeah, he would deserve any punishment he got, although I'd be a little surprised if he sees any.
That said, I've never thought that this thing was about him. I've said that here a zillion times. He was just the fast-talking, damaged, needy con man who was shameless enough to tap into what already existed. None of us saw how wide and how deep this thing was, but I have no doubt it began the day Limbaugh went national.
This is a fully separate, fully functional, fully self-contained ideological/informational ecosystem. It had been guided and nurtured by talk radio and Fox and the internet for years, but Trump came along and gave it a bold, brash, aggressive celebrity face. And these people latched on to him like their lives depended on it. This is a true, literal cult of personality.
So yeah, we have no choice, we have to at least try to make him pay. But even after he's gone, the core problem will remain.
