You are the one making the case that AOC has done it twice like Musk, so the burden of proof is on you to produce the evidence.
Musk's first salute is very close to the blood tribe member in the clip I posted. The second one is almost identical. It also came right after he spoke about the electoral victory being a great day for western civilization.
The video you shared is nothing like Musk or the blood tribe member. You are going to have to try harder to convince people of your false equivalence.
Do I think Musk is a nazi? No, but I do think he is a troll and an edgelord, and both are well documented. That being said, he seems to be chipping away at his plausible deniablity financially supporting Tommy Robinson, the AfD and a white nationalist South African
who has advocated for the return to apartheid.
