"portraying non-Western natives as evil savages."
I'm wracking my brains to think of some reason to imagine that the pre-Columbian Indians weren't evil savages. (Strain, strain...) Nope, can't do it.
"Second, Mayan city people are shown as violent extremists"
I find that use of the word "extremists" to be very surprising. Apparently it has become a generic pejorative among the eneuretic left, completely divorced from its original meaning.
"bent on harvesting innocent villagers to provide flesh for sacrifice and women for slaves"
IOW, business as usual among the stone-age primitives that occupied these continents before Christians arrived.
"Problem is, there exists no archaeological, historic or ethnohistoric data to suggest that any such mass sacrifices -- numbering in the thousands, or even hundreds -- took place in the Maya world. "
I don't believe you, Prof, because I well know that if there were, you'd lie about it.
"the new beginning for these lost Mayan people, the Apocalypto, evidently is the coming of the Spaniards and Christianity to the Americas."
God has a history of taking lands away from people who practice human sacrifice...or, perhaps, abortion in the tens of millions?
"The Maya were simple jungle bands or bloodthirsty masses duped by false religions, resulting in the ruin of their mighty but misguided civilization, and their salvation arrived with the coming of Christian beliefs saddled on the backs of Spanish conquistadors."
Truth stings, don't it, ya ivory-tower twerp?
"As archaeologists struggle to accurately reconstruct ancient Maya society"
Road apples. All the honesty in all the archaeologists in America, distilled and crystallized, wouldn't even be visible to the naked eye.
"Further, inaccurate representations by Hollywood of indigenous peoples as amoral, inhuman or uncivilized"
Nothing inaccurate about it, as you "archaeologists" really should know.
This is part of the continuing legacy of Franz Boas's struggle against the eugenicists, cultural supremacists (I think there is another term for them) and Nazis, on the one hand, and Margaret Mead's Barney-the-Dinosaur evaluation of Samoan society. It turned out the Samoans were "on good behavior" for Mead, who ate it up with a spoon because it met her own biases; she came pre-loaded, apparently, with an intellectual agenda that said that Western Civ is crazy-making bad and wicked and evil and stuff. As a result, she didn't record accurately some pretty dark things that were commonplace in Samoan society.
