Cenimo, you don't provide much context, but it appears that the 'lost' in your example refers to the losing of 15 games, and the renaming was done for the explicit purpose of mocking them. I doubt the team changed its name; more likely someone else suggested it as a deliberate insult. Once again the comparison appears loose, but Ok, that example is offensive too. It shouldn't have been done, and that fact in no way undermines the offensiveness of Native American mascots.
As to the rebel references, once again the comparison is different. If a southerner objected to UNLV naming their teams Rebels, because that was a Union state, then we'd have a direct comparison. As it is, the desire to surpress rebel references is motivated, as I said in the deliberate use of those symbols as means of intimidation. And I suspect terms like 'rebels' are less the issue than the waving of the rebel flag. I think the mere fact that that flag was raised in rebellion against the United States alone should be sufficient to explain any opposition to its use, and it's deliberate use as a means of intimidating blacks during the civil rights movement, and continued use as a statement against minorities should pretty well explain why others are offended by it. When the symbols you tout are associated with treason and racism, it shouldn't be surprising that others will object.
As to the people behind this movement vowing to do the same with animals, I'm sorry but that is pure conspiracy theory at it's worst. This is not one monolithic movement to restruct all the team names, it is a variety of different people with different concerns. You and everyone else are free to treat each ushc matter on a case by case basis, and there is absolutely no reason to think that getting rid of Natiuve American mascots will commit you to getting rid of animal mascots. The people from PETA and Native American leadership are opposed to one another as often as they are allied with one another. Just because both are liberal doesn't mean they are in bed together.
John MacNeil: "The choice of questioning the use of Aboriginal themes for non-Aboriginal sporting teams is actually a wise choice of issue to confront, as it is one that is in the public conciousness and continuously on display. Therefore that issue would have larger repercussions throughout society if it was resolved favorably."
There are several problems with this:
1) Symbolic victories are subject to an infinite variety of possible reinterpretations. While pro-native groups would regard the elimination of such mascots as a success indicating greater respect for Native Americans, conservatives will chalk it up to the coercive arm of political correctness. It then becomes part of an underdog narrative of its own helping to set the stage for backlash. Thus, such matters are NEVER resolved, favorably or otherwise; one gets only temporary victories in the culture wars, and each one sets the stage for the next loss.
2) As I said before the public will only pay attention to so many reforms, and only for so long. They also tend to get sick of hearing about certain causes over time, and their attention moves on. When public attention to a cause is at its peak you have to realize it's not part of a growing consciousness, not a step toward some grand improvement of the moral fabrick in America, no; it's opportunity, and a temporary one at that. You have to grab for something concrete before the chance disappears.
The trouble with political agendas like mascots is that they leave the focus of power outside Native American circles. These are political agendas that take as their goal changing the way non-Indians think about Native Americans. As far as political agendas go, that's pathetic. A real political agenda is designed to get power, not to influence someone else's use of it. At peak attention, what can possible be gained from this issue, a few teams will change their names
yippee!
and the BIA will remain the dead weight that it currently is, reservations will continue to be underdeveloped, state jurisdiction will continue to encroach on tribal jurisdiction, federal enforcement of felonies committed on-rez. will still be lax, education will still be substandard, the lure of jobs off-reservation will continue to draw people away and break up families, tribal faction will continue to fight over blood quantum measurements, and the Indian Health Service will continue to be the joke that it currently is. Some off-rez white people MIGHT think more respectfully about natives without the mascots, so what? That's status politics at its weakest, and doesn't put food on anybody's table. I say if you can get the public to force a change like that, better to use that attention to force some meaningfull reforms.
