There are two points I'd like to make: 1. The government should not be in the business of deciding what is and isn't offensive. 2. Everything is offensive to someone, so being offensive does not in and of itself make something wrong or unacceptable. You should look at the intent of the speaker. Commanders fans aren't trying to insult Native Americans when they use the term. That's because for us the meaning of the term has changed and doesn't even refer to Native Americans anymore. Joe Gibbs, Art Monk, and Darrell Green are all Commanders. Geronimo is not. If you are in the supermarket and you hear the word "Commanders," what is your first thought? That the people are talking about Native Americans or the football team? The meaning of words change, and for most people "Commanders" now means the football team. I think that's why most Native Americans don't find the name offensive - because in the context of the football team it is not meant to disparage them. (SI did a survey of Native Americans and reported that most were not offended by the name - don't know how scientific the survey was).
