I can only speak for my family, but growing up the grandson of the granddaughter of Chief running bull, Souix tribe, the only team she cheered as hard for as her huskers, was the Redskins. She nor her kin had any other affiliation with D.C. the Irony is, that's where most of the broken promises that put her in the reform schools to whitewash her and her family originated.
That's a narrow view of why I feel that this a vocal minority affecting this change. Glad I dont care that much but I'm sure she would be pissed R.I.P Gramma Jan. And go Niners. GBR
