when studying history, its always interesting to look at the opposing viewpoint of the same thing.
A good example of this is when America was expanding out west and "relocating" the native americans.
in school (the whole of it) the only real thing I learned about it was little big horn and a tiny bit about reservations.
but when I got to college I met a friend who is a native american and grew up on a reservation and wow, he makes it sound like Americans were doing what the nazis did to the jews.
where's the truth, probably somewhere in the middle.
The thing that worries me the most is schools and cultures that rewrite their history or ignore certain aspects of it. I've met people who refuse to acknowledge the holocaust or soviet prison camps, or even skew the events of hte Civil war (but hey, who knows, maybe all those people are actually right...)
