Trump goes straight to name calling. He is incapable of the approaches near the top of the pyramid.
I don't think that's true. He's published numerous detailed position papers that he's demonstrated an ability to defend. But he's often attached in such a puerile fashion he just responds on the level at which he was attacked. After all, why throw pearls to swine? His critics never admit the mud they're slinging, and pretend he's responding in a vacuum - it's absurd. But that's what PC enables, and that's why the left loves it so much.
