I just ran across this article from Th National Vanguard website on racial mixing. I've included the most important part of the article here which seems to indicate that mixed race cultures historically have always gravitated toward extreme violence.
the part he left out here is the brutal gang rape of women 40 times first before nailing them to the side of barns and the crushing baby skulls with the butt of their rifle. The men are forced to watch before they are shot in the head.
OK, i'll get right on that joo hatein train
