No surprise. Here in Green Bay, the Oneida tribe own a casino and give preferential treatment to non-white employees. In fact, black and white employees are passed over in favor of Hmong, Hispanic, and Indians.
I find it interesting that so very often when one minority group that supposedly suffered from a history of discrimination and ill-treatment gets into any sort of position of power or develops clout of any sort, the first thing they do is to discriminate against other minorities.
