I have encountered this "life was perfect before white men came to America" thing before. Substitute Africa if you like, the same meme is in the consciousness. One of the more amusing aspects of this is when you point out that they had slavery long before white people came along... and they tell you that it was a "different kind of slavery" a kinder gentler slavery one supposes.

I can't help but think that tax dollars are paying for at least some of the dissemination of disinformation here.
