My late friend Bill Safire, the tough and joyous New York Times columnist, once gave me good advice. I was not then a newspaper columnist, but he’d apparently decided I would be. This is what he said: Never join a pile-on, always hit ’em when they’re up. Don’t criticize the person who’s already being attacked. What’s the fun in that, where’s the valor? Hit them when they’re flying high and it takes some guts.
