Edit: Jesus fuck Lemmy, take a chill pill. It's making fun of the outrage, I didn't mean for it cause more of it.
I remember the speeches from Clinton and Obama. They were using the gesture to express a multitude of people. Meaning they were swinging their arms in a gesture to represent all people's in the audience. These pictures are just a midway on that. If you watched the speeches, Obama was noted for trying to make all people's represented and included. Clinton followed suit by doing the same thing. Elon Musk totally threw a nazi salute
