Speaking as a member of the Cherokee tribe I do not find the name offensive. Mainly because the image portrayed is a dignified representation and is not cartoonish. I've never been a big fan of the Cleveland Indian mascot representation, but to each his own. Perhaps it is because my family does not take everything seriously enough but my mixed family always had a great time playing up the Dallas Cowboy / Washington Redskin game.

We always referred to ourselves are redskins within our families there is no shame in looking different and instead we have always been proud of our heritage.
A better use of time and resources would be for white people and native american groups who oppose the Redskins name to focus on the deplorable conditions of most of the reservations in this country, where native american indians didn't integrate so easily into the american culture and instead have serious problems. Take time to examine the alcoholism, poverty and suicide rate then come cry to me about a stupid football team name. In a way the names of sports teams actually beneficially keep native american presence in the American collective consciousness. How many people are actually familiar with the Potomac name being representative of the Patawomeck or how the tribe helped integrate their image with Stafford Virginia's high school? Redskins, Braves and Indians keep the images alive and relevant. Imagine if they were all Jets, Cougars and Panthers, the cultural influence would be lost.
