I saw him first. INTJ.It's natural for anyone to be afraid when they make themselves public enemy #1 of the most unscrupulous nation in the free world. Even when that someone is a kick-ass INTP.
He has the classic "deer-in-the-headlights" INTP look. Also the trademark monotone. He feels "compelled" to talk. He's not interested in celebrity, it's a necessary evil. Hence, what you perceive as impatience. (IxTJs, otoh, love the sound of their own voices - almost as much as they love the smell of their own farts). Dropping out of formal education / the military / the system is entirely consistent with INTPness. As is his näive idealism. It's hard to imagine any IxTJ having a problem with "turn-key tyranny"....when he is holding the key.
If this were not compelling enough, he's much too cute to be any kind of J.
