Why is this OK...

Because to the best of my knowledge, no significant number of Irish or Irish Americans objects to it.
And this was not...

I don't see any problem with this one. But I'm not responsible for what a bunch of white people (the NCAA) do.
And it's irrelevant. You keep missing the point, or perhaps you're just trying to divert it. Neither I, nor to the best of my knowledge most Indians, have a problem with "Indians" or "Braves" or "Chiefs" or "Seminoles" or "Utes" or any names like that. But to me and to most Indians that I know, "redskin" is a racial slur.
That's what this is about. You and Captain Morgan keep pushing the slippery-slope fallacy. But that ain't the topic. The topic is one word: Redskins.
I'll ask the same question I asked Cap. Why do you even care? You're not a Redskins fan, are you? And I know from our interaction here you don't give a damn less about Indians generally, our ideas, our history, our problems, or our opinions.
I don't other than this is an example of a group that is being so hyper-sensitive that anything will 'offend' them.
So, I guess I'll ask the same questions of you that I never get an answer to from anybody else, not that I expect anything different:
Do you consider the term "n*gger" acceptable for general use?
Do you dispute that a substantial percentage of Indians consider "redskin" to be a racial slur, and pretty much the nastiest and most insulting of them?
And in all sober seriousness, here's one I'd really like an answer to: who gets to decide if a given term is unacceptable, society at large or the group to which the term refers? I ask because I can see both sides to this argument. On the one hand, American English doesn't belong to Indians, it belongs to all Americans, and shouldn't be ruled by one group that's only about 1% of the population. On the other hand, you could argue that Indians have a particular interest here.
