Correction -- white guys are banned from wearing headdresses in the stadium, not Native Americans. From the story, it appears that a white guy was simply wearing a headdress. He wasn't dancing around and making fun of Indians (sorry, Native Americans). He was wearing it as he watched the game. That, alone, was offensive to the Native American grievance-mongers who got in his face and demanded that he take it off. Whites appropriating "their" culture automatically is offensive.

As others have stated, it would have been funny if he’d come right back with

“I’m offended you’re wearing European style clothes!”
