He's obviously some plant or bad actor. First off he has a freshly shaved head. That and the brown suit (they wear brown shirts, right guys?) screams "costume". He then identifies himself as a "White Nationalist...White Supremacist". Almost nobody in the movement outside of the wignattiest of wignats describes themselves as a "supremacist". Funnily enough he goes on to talk about wignats...
But the real give-away is how he engages with Myron. All his questions are framed in trying to bait him into "bad optics" answers. He doesn't articulate his own worldview outside of a few stereotypical platitudes. There is no argument, just baiting questions. Then the cherry on top is the passive aggressive "I'm 1/4 ashkenazi" line. Because all White Nationalists are hypocrites that are part jewish or have a black great grandfather, right guys?
This video is a great teaching tool on how to spot fakers/infiltrators.
