Everyone who has eyes can see he did the Nazi salute.
Everyone has seen who Musk is - a drug addled internet troll who, without a doubt, told his mates, “guys, I’m going to do the salute on tv at the inauguration, it’ll be hilarious, and people won’t do shit.”
It was a Nazi salute, for the lulz. Musk is a fucking clown. He’s the disingenuous asshat engineer who argues in bad faith, “but how do you know it was a Nazi salute? How do you know I didn’t intend it as a heart going out gesture, never mind no one in history has done a heart going out/love gesture that was misconstrued as a Nazi salute.” Because I have fucking eyes.
