It’s like calling somebody white or black, merely a racial description which is not condescending or demeaning. We must always respect Native Americans.
Some whites are reddish in color, they may be considered redskins, too!
Some blacks may be offended for being called African-American, because they may not consider themselves African.
There are plenty of economic, social, and health problems Native Americans must deal with every day, problems we must address nationally, but the Washington Redskins must not be viewed as a racial topic, because it isn’t.
