Kauffman Stadium is surely among the least receptive public venues in Kansas City for displays of ambiguous sexual identity. This theory was tested Thursday afternoon. Royals fans were understandably cranky. It was hot, the home team was on their way to a 17-3 drubbing, and the stadium was packed with shrieking kids on a "school day" promotion. Two shirtless guys began taunting Royals fans. Their antics included embracing each other, dancing provocatively and waving A's batting helmets. It was too much for the Royals' constituency to absorb. Dozens of schoolgirls giggled and groaned. The Larry the Cable Guy-types surrounding me were flabbergasted. After several innings of escalating altercations, the Royals' security staff asked the men to leave.
