I also know how uncomfortable it is to acknowledge this. I even know that simple acknowledgement of this would conceivably get you fired or at least leave you persona non grata in your line of work. Let that sink in for a moment. Sort of like acknowledging that there are only two genders could conceivably result in similar consequences. It's a strange world, isn't it? I know you try to play these things off as right-wing boogeymen and hyperbole, but you and I both understand that if you stated on campus that the mean IQ for Asians differs quite bit from the mean IQ for blacks, or that gender is synonymous with sex, and there are only two genders, you'd be met with great hostility and calls for your termination. End of story, all feigning of ignorance aside.
Your point about the correlation between intelligence and education is correct, of course. What I think you have wrong is the apparent assumption that the rhetoric that bothers you the most emanates from lesser-educated folks in the opposing camp, the Deplorables. I think the people who hatch and generally disseminate the talking points and rhetoric that bother you most are counterparts in the rival tribe who are mostly college-educated. Many with college educations from prestigious universities.
