That is not quite as clear an insult as the finger scratching, but still it is disturbing. Think the MSM will pick up on it? I dont.
It definitely looked like a McCain arm gesture. If he is doing this there...he is probably doing it everywhere. Will be good to keep a watch and see if he keeps this up. Nail him! What a jerk....he’s going down...it’s karma. You don’t mock an American hero’s war injuries without a big payback. He’s going down...wait...he’s already going down and it will be a white woman and war injured true American!!!
A psychological survival tool and a 'craft' whereby you simply mirror others; while keeping 'yourself' to yourself.. .
That said, if you watch him; he makes incredible and some, very weird, gestures while speaking.
(Less 'weird' but curious; his constant pulling up his pants; adjusting his waist-band/belt...'WHATever'; did leave me wondering, what is his problem; that a simple tightening of his belt could not remedy.)
Think when he knows he is approaching/saying what is in truth; unacceptable; his gestures become both deliberate and unconscious distractions. And he IS good at crafting his body language - and words. We KNOW, he is practiced.
