You may have read about a vote by the sportsmanship committee of the Wisconsin Interscholastic Athletic Association (WIAA) to ban bare-chested spectators and fans who paint their chest at indoor high school sporting events. The proposal will be voted on soon by the WIAA's governing board. In my view, the WIAA is doing the right thing.
