New York sports-radio station WFAN has, surprise surprise, advocated rudeness toward Red Sox fans with its latest subway ad. "Always offer your seat to a pregnant woman. Unless she's wearing a Red Sox hat," the ad advises passengers. Nice. Rowdy, locker-room-culture sports ads are one thing, but this isn't even a celebration of the game. It's just promoting silly tribalism, and it's not even clever. WFAN is just lucky Philadelphia fans are around to make them look civilized by comparison.
