swap racist with derogatory and you get the idea. Btw, what are the three?
I am always amazed that people are no longer educated, but are politicized. Do your own research. There are three recognized races. There are several ethnic groups within the racial groups. Ethnic considerations are not assumed to be "racist". Try Anthropology 101 for starters, and if you choose to throw "race" around, at the very least, get a basis.
