Sure, way to young for that; but he is very much cut from the Nazi adjacent, racist, antisemitic, antidemocratic, technocratic views of his whole heartedly apartheid embracing grandfather Joshua N. Haldeman.
His grandfather wrote his tracts to raise an alarm about what he called “mind control,” on the radio and television, where “an unconditional propaganda warfare is carried on against the White man.”
Absolutely no point arguing with these people. They are so ideologically captured that it's pointless trying to discuss anything with them. Just move on. Everything and everyone they disagree with is "nazi" and if you say anything contrary to that you're a "nazi" also.
He does the same exact literal Nazi things that Nazi did and has Nazis in his family tree. You'll need better arguments to defend him than just "I don't agree".
