WASHINGTON -- “Shaming,” the modern if tedious trend of shaming the shamer for criticizing anyone, has rendered us incapable of making rational judgments or speaking freely. If this seems too strong an indictment, consider that “the porn star and the president,” a pairing made necessary by current events, is no more shocking a phrase than, say, horse-and-carriage, which in an earlier time, some may recall, went together like love-and-marriage. Or vice versa.
