Bottom line, if he were actually interested in Nazism as an ethos, I don't think he would publicize it. Not at this stage, anyway. If you could actually ask Fr. Occam what he thinks about Musk, he'd probably say, "He just gets off on shit-stirring, that's all."
In that respect, he has found a kindred spirit in Trump, and he rationally sees an alliance as the only way to keep his business interests healthy over the next several years.
Steve Bannon's dictum still holds sway, even if the man himself is on the outs with Trump: "The real opposition is the media. And the way to deal with them is to flood the zone with shit.” Say what you will about Musk, he's really good at that.
There's a clip of Elon's dad saying that his caretaker had read the book to him, translating along the way, and so he'd known the name. It also coincides with an in-law's name, so he took that coincidence as a sign. But Errol really did say that the name came from the book.
He's been promoting Nazist ideas for a year.
And he took part in the AfD's big meeting (you know, the closest thing to a modern Nazi Party in Germany) downplaying what the Nazis did.
If he acts like a Nazi then we need to call him a Nazi and stop coming up with weird excuses for him.
Try moving in Japan, Australia or NZ then to find out how nazi they are.
It is true that Musk himself is checking more and more of them every day, though.
Musk is showing Trump his willingness to play the kayfabe game. It is a rational move on his part, sadly, because his businesses are so critically-dependent on a good working relationship with Federal power.
He probably isn't really a Nazi. That would imply that he considers himself to be part of something larger than himself. As Vonnegut said, though, we should be careful about what we pretend to be, because that's what we tend to become.
