Did you know that at one time the Bronx Zoo kept an African Pygmy as a speciman? What was that all about. Eugenics. The science of the times had this belief in some people being better than other people and some people-looking somethings were not really people. So whenever you start saying that some people are better or more human or more perfect than others based upon their ethnicity, color or language, you are on a very slippery road. It is a kind of social Darwinism with the idea that different races represent different levels of evolutionary development. It will end up in violence. Religious scriptures challenge this way of thinking, but many a person in the pew or bench, hold to this evolutionary strata system.
