Of almost anyone on this forum, you shouldn't be calling anyone else dumb. You remind me of the deleted scene in Terminator 2 where Arnold tells John that his learning capabilities aren't activated. Your inability to absorb new information and your confidence is amazing, you're a walking Dunning-Kruger.
Aside from who Elon cozies up to and members of his family which you probably don't know or care about nor the German party he supports, what he did is very clearly a Nazi salute. He didn't put his arm out to wave, he didn't do the Kamehameha stance like BJ Penn, he didn't dab, he didn't casually put his arm out, he full on, 100% energetically Sieg Heiled, and just to make sure no one got the wrong impression, he did it twice. It's not a liberal or two questioning a questionable gesture, Elon did the thing, ain't no question about it. And he did it at a presidential rally on MLK day. Shameful. If you think that wasn't intentional I've oceanfront property in Arizona to sell you.
Anyone defending this a moron, a "trigger the libs" loser, an actual racist, or a troll, or all these things. Edit: Or, I'll be charitable, someone in denial. Serious denial.
