"Our new friend is a racist -- should we dump him?
My husband and he have so much in common -- but his beliefs are pernicious and wrong!

It is difficult for those of us with all the correct beliefs to extend courtesy, love and understanding to those with mistaken beliefs. But it is an affliction of your time to believe your own beliefs -- to believe your own beliefs are the only ones that matter and are correct and represent the pinnacle of social progress. If you take an imaginative leap to the 12th century, or the 18th century, or the 1930s, you will notice how radically beliefs change. We who are now alive think we know what is right and correct, as did the Spanish in the Inquisition and the Protestants in the Reformation and the Maoists in the Cultural Revolution; it is the privilege of those on top to think they know what is right and correct. It is a nice privilege indeed. Doubting ourselves is hard.

Even if we are correct in believing that those of us with the correct beliefs represent the pinnacle of social progress, we must also recognize that... some are slow to accept cultural progress and scientific knowledge.

You can call them names if you like. You can call them racists and bigots. You can exclude them from your company even though you really like them as people...

We ought not let them rule our nation, of course. But we ought not exclude them from friendship. I just think lots of us are pretty dumb, and we're not all that virtuous either, and big deal. I'm not so impressed with our own assumed air of virtue, we liberal coastal elites. I don't think we're all that morally superior to the racists and sexists we can so easily pick out of the crowd and condemn. I think in fact that our frequent presumption of moral superiority is a deep character flaw that blinds us both to the vast virtue around us and to our vast capacity for growth. And more than that: Our air of superiority bores me. It bores me how we talk. It bores me how seriously we take the liberal taboos, how easily we are stopped at the borders of good taste.

In fact, I am rather drawn to the bad man, the racist, the reprobate, the criminal, the idiot, the one who doesn't get how he is supposed to behave. He unwittingly shines a light on the dark side -- and even that is condescending, isn't it, to assume that the only virtue we can find in those of a lower caste is one they are not even aware that they are expressing?...

Can you love someone who is deeply flawed? Do you have the courage to do that? Can your love be tinged with disapproval and still be love? Can you heatedly dispute on matters of social beliefs and still remain friends? I hope so. I hope you can do that. I also hope you can find persuasive materials to show that the beliefs of your friend are groundless and pernicious, for that is today's correct belief, and it is the one true belief, and it is the belief that everyone should have."
