Speciesism

Speciesism was a belief that one species was inherently superior to another or all species.

Overview
It was found in cultures across the Galaxy, and for various reasons, ranging from religion and race to simply an overinflated sense of superiority. It could range from single individuals to the entire species. Some races, like the Gran and the Givin, were mildly speciesist, and still able to work with other races. Others, like the Hutts and the Chiss, considered themselves inherently superior, but still managed to work along side other races on occasion. And then some races, like the Ssi-Ruuk, the Yevetha, and the Yuuzhan Vong, considered all other races an abomination. An especially prevalent type of speciesism was Humanocentrism. Some believed Zabraks to be speciesist due to their extreme amount of determination and willpower, although this was not true. A notable Human speciesist was Count Dooku, who considered all non-pure Human lifeforms to be disgusting and inferior. In response to such sentiments, Aliens sometimes formed anti-Human sentiments.
