Molyneux was always like that, but because his videos were like half an hour to an hour of him just sitting in front of a wall nobody but the cultists probably watched his whole videos. He had like one good debate with some weirdo academic and parlayed that into wank dad success. I remember on a few libertarian sites people initially liked them but then were like he's a weirdo and boring and isn't as smart nor as well read as he proclaims, and then it got to just making fun of him. It was places like Lew Rockwell which entertains the whole white male genocide problem more often where he still had fans by 2014 or so.
I haven't probably watched one of his videos in at least that long so I don't know if he's gotten worse, or into more alt-right/MRA stuff. Last one I did, I remember he was completely misunderstanding some basic libertarian point (ala something a "philosopher" should know because it's from Mises or Hayek or Rothbard or whatever) while giving an account of history that was less factually wrong than presented so confusingly that it made zero sense, and the video was of course just him sitting in front of a wall so there wasn't actually any kind of well, anything to help you keep track of exactly what he was saying or the order of events or anything .
I do sort of remember my personally lumping him in with the (often Canadian for some reason) Objectivist types, even though I don't think he's an Objectivist, that sees a whole "clash of civilizations" going on and argues that it's not a rights violation to murder people in countries with less rights than the United States/Canada because countries that have more freedom are justified to "liberate" less free countries. It was because he was saying some similar stuff about Muslim countries and Islam. Some other wank dad people like Sargon have occasionally expressed similar sentiments about people who live under Islam.
