That’s a Roman Salute (that never existed in Roman Times, just fascist modern countries).

He’s autistic, it’s not his fault (also they’ll never hold jobs or be successful).

His heart goes out (to other white supremacists in the crowd who cheered loudly for his salute).

He’s just waving to the crowd (while promoting white fascism).

He got a little over excited (and forgot he was being recorded?)

What a fucking weird loser.
