I think Milo is a scumbag, personally, but where did he self-proclaim that he's a white supremacist?

>Alex Jones testified to being a performance artist

No, he didn't. His lawyer attempted to argue that he was during a lawsuit, as a defense against full culpability for his actions. Lawyers (understandably) try to pull out everything they can to help their client. There's no evidence Jones himself has ever said this or thinks this.

Although most of his non-watchers seem to think he's just a con artist, after watching a cumulative dozens of hours of him on camera over the years, I'm convinced it's not an act and that he genuinely believes pretty much everything he's saying (except for cases where he's attempting to do a comedy bit). Unfortunately, a lot of people in the US believe all of the things he believes - and not necessarily because they're hearing it from him. They all drink from the same watering holes. In my opinion, this is why it's actually a lot more frightening than con artistry or performance art.
