So you do agree that the use of Redskins is offensive?
To the other point, I stand by my original comment questioning the sincerity of the co-opting of indigenous culture for the purposes of deriving mascots, particularly for profitable enterprises like pro sports, with long histories of exclusion on the field, in the stands, and among ownership. Yeah, that seems exploitative to me under the conditions of our history.
Generally, I think it's distasteful in any society to market and profit off of people who have been horribly mistreated.
In cases where agreements have been reached with local tribes, I think that's a better approach as opposed to the attitude of just continuing with something because that's just the way it is and we like it fine. I do, however, find the term Redskin to be particularly offensive and outdated.
