Intellectualism isn't predicated on being correct. There are communist intellectuals, radfem intellectuals, etc. The major alt right intellectuals of note are people like KANTBOT, Frame Game Radio, and the bleedovers from the manosphere like Illimitable Man. I've debated with them multiple times on Twitter as a means of reaching out. They take it seriously and aren't pure ideologues.

Edit: It should also be noted that even the widely-hated Richard Spencer is not a moron. He has a Masters in Humanities from the University of Chicago, and was a PhD student in European intellectual history at Duke until he left after 2-3 years to pursue activism.
