Are those channels supporting his views

I'd say they are supportive, honestly.

You probably know the type. Some account probably called something like "FreedomJustice&TRUTH" that only has videos of him, doesn't really say much in the title, and all of the comments basically agree. Then disappears forever, and you can't find the videos ever again. ... until the next one.

The algorithm actually fed me some of his videos.

Especially since you tried to conflate him with Patriot Front.

I honestly wouldn't put him that far off. He really does appear to be an American Fascist, and frankly, I think that's really what AF stands for, not America First.
