The term Mongoloid is a variation of the word "Mongol", meaning "Mongol-like". It was coined as a racial category to describe the distinctive appearance of East Asian peoples. Variations include Mongolian race, "Sinoid" or "Mongolid". Today it is most used in discussions of human prehistory, historical definitions of race and in the forensic analysis of human remains. The concept's existence is based on the now discredited typological method of racial classification. In forensics, Mongoloid is considered a skull type that is used to determine the probable soft-tissue reconstruction of discovered human remains.
Now people with downs usually have a enlarged forehead. They are being referenced when using mongoloid. So you are insulting the Asian race by referring mongoloid as "retards"
