I find it fascinating, this 'time vs virtuosity' struggle. Many people think the longer a belief is held, the more true it probably is. That, of course, is false, but nevertheless many subscribe to it.
We can call the long-held idea is 'tradition,' which makes it seem more true/likely/important, but again, false.
We also have many who believe the more people that hold an idea/belief, the more true it probably is. Another fallacy.
So it genuinely doesn't matter how long the football team in Washington DC has been called the Redskins and it doesn't matter how many see nothing wrong with it and how few do, it's an obvious racial slur.
Fixing it is akin to wearing a mask, hell, it's even less than that. Fixing it is akin to not actively picketing a gay wedding. It doesn't directly affect anyone. It harms no one. People get bent out of shape about it because of ideology, which can bother you all you let it, but has no real bearing on the world at large.
I've already shared my stories about liberal white people being the ones on the front lines of this, and announcing HS football games between native players, with one team being called the Redskins. But their apathy, too, doesn't make it magically acceptable. They're facing their own indoctrination, apathy, and bigger problems (running water, electricity, radical poverty, etc).
It's amazing what can bother us so much that has zero direct affect on us. I bet that's mostly an American thing...but I shouldn't say that, because I'll be told to move to Norway.
