The fact of the matter is...in virtually every study and every poll done of Indigenous people, fully over 95% of Indigenous people are NOT offended by these nicknames. i.e. Holden Armenta with KC Chiefs face paint and his father Bubba. FYI, they BOTH have more Indigenous blood than most of the people doing the complaining.
It is the other 5% or more who are just loud and do find offense. Why? No one really knows for sure. They might tell you why? But is it true? So, should the change be made to satisfy the 5% of those people even when 95% don't mind? Or is part of the change being made to make some Non-Indigenous feel better about themselves. Symbolism over substance.
Do these changes actually make their lives better? Does it enrich them more? Does it open up new "opportunities" for them? Are their living conditions and the neighborhoods they live in improve vastly, or at all?
Have any of them lost job or career opportunities because Washington used the nickname "Redskins?" Were their homes and property burned because Cleveland used the nickname "Indians?"
I think the changes will continue to be made. Fine. But no improvement of substance will occur in the lives of those complaining. None.
