Yeah, that's typical human behaviour I guess. So much for progress huh?
As for your last, the "lies" comment; history is written by the victor, no doubt. I'm less inclined to allow my love of history to become overly politicised though, I don't want to taint my love of history and who was right if wrong or hard done by doesn't matter.
If you like reading, might I suggest, The Last Duel, by Eric Jager, based on a true event. It was made into a pretty good movie as well and one compliments the other quite nicely. Read the book first. Fascinating reading.
