Setting aside the fact that 100% of the air has been let out of that accusation and nobody takes it seriously anymore and that's probably dangerous, whether or not he's a Nazi, which I doubt very much that he is, is immaterial. Disinformation is basically the stock-in-trade for politicians, it is not illegal. This will likely be and certainly should be an acquittal on first amendment grounds. It is political persecution, just like Saudi Arabia imprisoning someone advocating for women's rights.

How people don't see where this kind of thing is leading is beyond me.
