Wallace McLendon of Chapel Hill penned an enlightening op-ed about his encounters with former friends who had been seduced by the dark side of money and bigotry, and I think it's as good a time as any to face some undeniable truths. Topping the list of those truths: Friendship requires at least a modicum of respect. Friends are somebody you can come to with your problems, and maybe together figure out the best way to solve them. Friends are also there to keep you in check, to stop you from buying snake oil and other wasteful ventures. But how can you respect somebody who judges an individual or an entire race based on the color of their skin? How can you respect somebody who worships at the altar of Faux News and Breitbart, or whatever source of "news" that reinforces their prejudices while wildly misinforming them? The answer is, you can't. You might be able to tolerate such a person in short bursts, as long as the door is in sight. But true respect is simply not in the equation. Nor is true friendship, so cutting that person loose is not something to feel shame or regret over.
