There are other offensive names in sports.
If Indian nicknames are offensive , then......
Pittsburgh Steelers offends real steel workers
Dallas Cowboys offends real cowboys
LA Angels, San Diego Padres, New Orleans Saints are offensive to the Catholic church.
Milwaukee Brewers offends real brewmasters
Green Bay Packers offends real meat packers,
All the animal nicknames offend PETA types.
Etc etc
I thought Green Bay was offensive to the Fudge Packers.
