If it was something that came out of the blue, I might be more inclined to give the benefit of the doubt, but the man follows, regularly retweets and converses with actual (as in, they call themselves that) Nazis on Twitter.

It just shows that the mainstream media (and the ADL) aren't really interested in the truth.

It was a Nazi salute without a doubt. The only question is if it was accidental or intentional. Musk being a far-right operative and making a bunch of Nazi puns as his response instead of an apology for the misunderstanding makes it clear it was not an accident.

I’m pretty sure what you mentioned are principles used in courts of law. As a rule, journalists can and should call a spade a spade. They don’t need to prove beyond reasonable doubt what he was thinking.
