You can't silence someone for saying the truth if it didn't say anything true to begin with.

Gotta add "Bush did 9/11" and chemtrails to that list. He also believed that there were mind-control agents present in vaccines and disinformation campaigns that all major governments, corporations and scientists were in on.

He would constantly refer to himself as "enlightened" and everyone else as "shills" and "brainwashed" all the while acting like condescending, self-righteous asshat and worded everything like an idiot child making a dim-witted approximation of what "smart people" sound like in cartoons.

People would regularly ask him to present evidence to back up his views only for him to claim that he had tons of evidence but would not be showing it because we are all too small-minded to appreciate it. At one point he claimed that empirical evidence has less truth to it than what comes to him in prayer and meditation. He also had a strange habit of calling out (and frequently misidentifying) logical fallacies only to shortly after commit said fallacy himself with no apparent awareness of his misstep. He liked to say that everyone else was "thinking with their reptilian brains" while he was the only one being reasonable all the while making nothing but manipulative emotional appeals and relying on shock, even going so far on one occasion as to post a picture of a dead baby, prompting mod action.
