I find nothing racist about these movies. The people that find these types of films racist are the same type of idiots that will try to find something racist about a peanut butter sandwich.
In my opinion the message of these types of movies is not that the 'supreme race' comes along and saves the natives, but the oposite in fact. The message I get is that the 'supreme race' is so ____ed up morally, corupt and basically a ____ bag breed of big caca idiots. When a member of the 'supreme race' is taken away from his own peole and shown a different, more tree huggerish-love thy neighbor-war is not the answer-hippy-spiritual-ect. way of life, he sees the coruption and utter fail of his own race and becomes a 'better' being for his time with the natives. Thus turning of his own race, having now realized he sucks, his race sucks and they derserve to die for their failings as a whole.
