A couple of things. I don't buy the analogy. There is no pro-team named after a slur. There are leftest groups whose agenda is to push victim ideology that try and make them slurs, but they really are not.
And yes, the "over it" is, well wrong. They are not. They are still going after 95 year olds if they can get them. But I think what he might be noticing is that Jews have, despite being persecuted where ever they are, have done remarkably well. The same can't be said for most Native communities. There are many factors in that. Team names, I don't believe to be one of them. Embracing victim ideology, I believe is.
