When is it right and when is it wrong?

I heard in a commercial for Thursday Night Football that this Thursday the Washington REDSKINS will be playing the Philadelphia Eagles.  Because of the recent name change at North Side High School and the subsequent raising of my awareness of things that are politically correct I immediately assumed that they must be redskin potatoes. But no, I googled them and there was their logo - a fierce looking native American warrior with headdress (sound familiar?). I'm so confused.  Why is it ok for a national team and not for a high school? I wonder what the Washington Redskins' new logo will be? I wonder when they'll be after my Woodlan Warriors?
