Dont know when the last time you were at Little Big Horn, but it has succumbed to political correctness long ago. I remember going there as a kid, and hearing the story from a park ranger. My last stop there was about 7 years ago with my kids, and the park service had a native storyteller on staff give a 2 hour presentation on the indians side of the story, and how bad Custer was. The gist of the presentation was that this was not a national monument, this was a national tragedy, and that the white man was wrong and bad.
I agree that Custer got what he had coming to him but it was too bad he dragged all those other men with him. I have seen the native American shows on TV about the battle and while I found them interesting, they were certainly biased. Not surprising.
