@Fatal Freedoms,
I am not certain that it is all racism on their part either. They appear to be in great fear of losing something. This might be a clue:
For thousands of years, western europeans have been reputable for being obsessed with heroics. Obsessed even to the point of fabricating evil where none exists.
So would people demonize another race for the land, the ticker-tape-parades, the drunken slaps on the backs? Or something more lucrative?
I once heard that following the massacre of many Navajo-Apaches in Utah...the Hierarchy took two of the cavalry men on a ride that freightened the crap out of them. They then questioned them. "Why did you kill all those people?". Their reply was that an old Irish wives tale about ancient Elves being an incestial race and the features of the tribe led to believe that they could have been part Elf. AKA - genetically warped.
The next question was of course...had they done a blood test. Their reply was "No", "Because they did not actually believe they were genetically warped". The next question was: "So why did you kill those people?". Their reply was "Because the women were freightened".
It is said that no-one believes that the women were actually freightened of it. So....they did it for the sake of sexual prowess? That is the likely guess.
