If it was intentional I don’t think he would choose this venue. Trump has gotta be so pissed at him for stealing the media spotlight and making him look bad.
Fundamentally I don’t think he thinks of himself as a neo-nazi whether or not he functionally is one. And I don’t think he’s bold enough for a dog whistle this blatant even if he does.
Every now and then a little devil on my shoulder says “you should set up a cluster computer that serves a secondary function as a smart space heater” and it’s gonna be really hard to ignore if the deals are good enough.
