It's hard to like stupid people, so it's logical that you won't like people if you think you're smarter than everyone else. He'll either be smarmy or condescending, depending on the circumstances and audience, but won't enter into a conversation with someone else as an equal.
There is no genuine spontaneous social interaction, just calculated resonses and manipulations.
Anyone he feels superior to, he dislikes and views as inferiors,
but I’m sure he REALLY loathes those who DEMONSTRATE intellect superior to his own.
