Calling two fascist salutes an "extension of his heart to the crowd" is as dishonest an argument as trying to call them "Roman salutes" or trying to claim that he didn't know what he was doing.
Musk knew exactly what he was doing. He enjoyed doing it. It's who he wants to be. It's who he is.
To say this means you consume misinformation on a regular basis. If you watch the whole video he's extending his heart to the crowd. Further the "double our H1B" guy obviously isn't a fascist, he shares no ideals or political interests with fascism.
Claiming all your political opponents are fascist/socialist/demons/etc is a low-IQ argument and not conducive to meaningful discussion.
