Sorry, but this whole article, your fear,  is based on an assumption?

"I would HOPE that basic racism were not a driving factor, since I know that neither of my own friends".... "But I FEAR that, as much as these friends would be sure to deny it, racism IS the true darkness at the heart of the matter"... "perhaps beyond their conscious thoughts"  (In other words, they are so racist, they are too dumb to know it.)

"I would hope" - "but i fear" - it "IS" -
you don't know it for certain, no where in the article are you quoting them "they said" or "they told me". but you conclude by your assumption that they are both racists. 

And by the article title questioning "who" of the masses, implies and must equate that anyone that voted for trump, is also a racist ? Or is that, you can only be racist if you are white ? all of the non whites that voted for trump, how do you label them?

If I was your friend reading this, I would probably be offended. You might want to call them.
