TBH, I personally don't mind the Redskins football mascot, but it does indeed have a pretty racist tone to it. Native Americans are not just some savage animals to be used as a mascot. It's like making a team called the Gringos or Yellowskins.
Having known plenty of native Americans, I feel for them, more than I do any other disadvantaged race in our society. They are generally isolated from American society in ways that Africans or Hispanics never have been and most of their culture has been completely wiped out. What remains of it has been taken over by money, stereotyped and sold by the wealthy (both native and white alike). The worst part is that these stereotypes have become so deeply embedded and the disconnect between the two societies so severe, that today, even things that would normally be considered racist towards ethnicities, is not considered racist toward Natives.
I think it's some seriously fucked up bullshit how Americans do not make more of an effort to remember and honor the original people of this land. We'll devote an entire month to slavery and black people while turning Thanksgiving into a stereotyped whitewashed charade of bullshit.
In any case like I said; I personally have no problem with the Redskins mascot (perhaps a name change, though?), but blowing it off like our history is nothing, being part of the largest sports/entertainment franchise in US history, is shameful.
