. . . is to imagine a team named the WHITESKINS whose mascot is a proud white warrior. But the team’s owners, players and fans would belong to another (majority) racial group.
The decision points out true laches issues, and the the evidentiary record isn’t stellar, but in the end the word REDSKINS defines a minority group by a derogatory reference to the color of their skin (Native Americans’ skin, after all, is not red). REDSKINS is a racist term. The team should migrate away from the name.
