Certain views on human "races" are incompatible with intelligence. A highly intelligent individual may instrumentalize useful idiots through emotional and conspiratorial agitation, but they wouldn't be honestly convinced by these narratives themself. Not these days, there is too much scientific evidence to the contrary. The far right mob is easy to rule, if you can free yourself of empathy, dignity and honor. The people in power are not true believers, they are psychopathic opportunists.
