My Research Goal

My goal is to research the terms and words that are used as racial how they may or may not evolve. this is very important to me because i want to understand how these terms came to be. wouldn't you? so far it seems most of the terms evolve with society. And the evolution of their stereo types, for example. mexacan people because of their diet, are often called beaners. Wheather this is appropriate or not, it is one example.
