Xenophobia

Xenophobia is the fear and hate of things or people foreign or alien to the person (xenophobe, xenophobic) suffering from it. Some medical doctors believe xenophobia is a psychological condition, while others believe it to be a racist condition.

After the Xindi attack on Earth in 2154, xenophobia levels on Earth were higher than normal. An anbry bar patron took offense to Enterprise Doctor Phlox, a Denobulan, frequenting a San Francisco bar, resulting in a bar-room brawl. The Xindi attack was also one of the main reasons the xenophobic Terra Prime movement took hold. 

The Founders created the Dominion from xenophobia, with the main mantra of their government being the Founders' order should rule over the chaotic nature of solids throughout the galaxy. 

Cardassians also tend to be xenophobic. Cardassian Central Command ordered scientists to genetically alter soldiers to build upon their xenophobic tendencies, but the scientists failed, with the failed experiments left aboard abandoned space station Empok Nor. 

The Bajoran Alliance for Global Unity felt Bajor was for Bajorans only and all other races -- in their eyes, inferior -- should be expelled. 

The Bolian Isolationist Movement felt Bolians would lose their cultural uniqueness with Bolarus IX's involvement with the Federation and on-again, off-again conflict with the Moropa. Sometime after 2348, the Bolian Isolationists were exiled from their homes and founded New Bolarus. (: "Oh, What A Lovely War", "Howl")
