BS!
Most American Indians are proud of their red skin and don’t mind a sports team appropriating their fearsome fighting disposition and skills to represent their team. It’s an honor to them, not deprecating. But you can always find a few bellyaching ne’er-do-wells who take offense.
The ones who are most upset about the name REDSKINS are lilly-white rich liberals, often employed in academia.
Or the media.
Excuse me, but Indians don't have "red skin" unless they have painted it red.
Most real Indians like being honored by sports team names.
Leftists pretend to be offended so they can act morally superior.
