People who are socially awkward do not tend to accidentally do a Hitler salute. Twice. With gusto. At the White House. I'm socially awkward. I have managed to not even be close to doing it. I have found it very easy to avoid accidentally performing a Hitler salute.
Maybe they do after documented instances of retweeting neonazi posts. And after publicly supporting the closest thing to the successor of the German Nazi party, AfD. And after calling for the release of a self-professed and documented fascist asshole in the UK. I don't know. Few people have that pedigree, after all, be them socially awkward or not. I'm not sure even being high as a kite on ketamine might do it, but I'm not sure. I think my employer would frown upon me being high as a kite on ketamine.
If he wanted people not to conclude he leans that direction, it would be pretty easy not to accidentally do these things over and over. Unfortunate. But here we are.
Do you think members of the KKK are wearing those robes and funny hats because of social awkwardness too?
