Yes, I know. The terms "common sense" and "liberal" do not generally go together. They are as oil and water or perhaps sugar and salt.

However, Nick Cohen writing in The Guardian has some words of wisdom for his friends on the left regarding attacks on Sarah Palin:

But instead of following a measured strategy, they went berserk. On the one hand, the media treated her as a sex object. The New York Times led the way in painting Palin as a glamour-puss in go-go boots you were more likely to find in an Anchorage lap-dancing club than the Alaska governor's office.

On the other, liberal journalists turned her family into an object of sexual disgust: inbred rednecks who had stumbled out of Deliverance. Palin was meant to be pretending that a handicapped baby girl was her child when really it was her wanton teenage daughter's. When that turned out to be a lie, the media replaced it with prurient coverage of her teenage daughter, who was, after all, pregnant, even though her mother was not going to do a quick handover at the maternity ward and act as if the child was hers.

English leftists made the same mistake of allowing their hatred to override their judgment after the Iraq war. If they had confined themselves to charging Tony Blair with failing to find the weapons of mass destruction he promised were in Iraq, and sending British troops into a quagmire, they might have forced him out. They were so consumed by loathing, however, they insisted that he had lied, which he clearly had not. They set the bar too low and Blair jumped it with ease. 'When a man believes that any stick will do, he at once picks up a boomerang,' said GK Chesterton, and when the politically committed go on a berserker you should listen for the sound of their own principles smacking them in the face.

Journalists who believe in women's equality should not spread sexual smears about a candidate, or snigger at her teenage daughter's pregnancy, or declare that a mother with a young family cannot hold down a responsible job for the pragmatic reason that they will look like gross hypocrites if they do. Before Palin, we saw hypocrisy of the right when shock jocks who had spent years denouncing feminism came over all politically correct when Bill Clinton had an affair with Monica Lewinsky
