The choice of name was not shameful. The Indians were born in 1915, long before anyone considered it disrespectful or offensive. The racist caricature Chief Wahoo didn’t come into existence until decades later. Maybe you can argue that the shameful part of their history starts there. Certainly by the time the protests began in the 1970’s. Obviously its crazy that it took 50 years to finally effectuate the change.
Still, I find it hard to apply modern ethical standards to periods of time where none of this was ever a thought. And I don’t think that the franchise should be ashamed that they were the Indians. There was a long period of time where they carried the name without a hint of controversy. The shame is that it took them 50 years to change after the affected groups started voicing their concerns.
In any case, the name “Indians” meant something special to a lot of well-intended folks. It would have been nice for them to break the curse before changing the name.
Just an opinion. Your mileage may vary.
