Take this with a grain of salt, since I'm talking about, as discussed, his public persona, but I watched his video the other day and the first phrase that came to mind to describe him was, "smug little prick". Now, that's not the sort of language I would normally use around here, but we were already on the subject of presentation, expressiveness versus politeness, etc.
