Don't be cruel. Elvis said it and it's true. We all experienced cruelty back in our playground days, boys who beat up on the timid, girls who made fun of the homely and naive, and most of us, to our shame, went along with it, afraid to defend the victims lest we become one of them. But by your 20s, you should be done with cruelty. Mr. Trump was the cruelest candidate since George Wallace. How he won on fear and bile is for political pathologists to study. The country is already tired of his noise, even his own voters. He is likely to become the most intensely disliked president since Hoover. His children will carry the burden of his name. He will never be happy in his own skin. But the damage he will do to our country — who knows? His supporters voted for change, and boy, are they going to get it.
