And I'm getting wayyyy too political here probly :- ) but if a man's own posse considers him "crazy" then I think we're off to a bad start setting him as an icon of all that America stands for.
A balanced view of the Euro-Indian conflicts is next to impossible to get to any more, so you'd have a tough time DISCUSSING this issue, no doubt. SSI might be one of the few places you could do it.
e.g. I can't find a single website discussing "Apache atrocities" that does not attach "alleged" Apache atrocities. Pointing out facts yea and nay is one thing; obfuscating a discussion until it's impossible is another thing.
There were so many peace-loving, harmonious, Zen-like collectives on the continent in 1500 A.D, bothering no one, living in a rational way. Life lived in an almost idyllic way. Shame that people such as Crazy Horse can't be discussed intelligently.
