In this country, and in our culture, racism is indeed based solely in the white community. Bigotry, however, is not. Anyone can be a bigot. However, in order to be a racist, one must believe that one’s race is superior to all others, and support a culture with those standards. And in this country, only the whites have accomplished that in our history.
When you can find a cultural standard in our country where white people are afforded fewer privileges than non-whites because society deems them inferior as a race, let me know.
