Its a sad commentary on where we are today in the US. You would have thought the sixites and seventies put an end to this foolish and hateful behavior, but we see the old demons cropping again as the Aryan Nation, Skin Heads, American Nazi Party and the Ku Klux Klan.
In other regions of the world we see the same games only the names are changed. Whether is ethnic cleansing or genocide its all the same basic behavior. It makes you think its something burned into humans as a species that we seem to like to gather in small groups and persecute others. Even after thousands of years of experience and tens of millions dead you would think we would have had enough of this behavior and stamped it out.
Its a safe bet society never will be free of this cancer.
