I wonder if the anti-semitic thugs were white or non-white Caucasoids? Racial tension and ethnic violence is strong evidence that humans are tribal creatures who genetically evolved to side with their group, since their group shares copies of their genes.

High IQ peoples tend to defeat lower IQ peoples in military conflicts, but I wonder how well the same correlation holds when this kind of stone age violence occurs.

I find it all very depressing. You would think by the year 2015, humans would have overcome their primitive ethnic impulses.
