Ethnocentrism could be considered a complex of some kind. It refers to having the feeling that your own culture or group is superior in a way. Although no culture, ethnicity, or group of people is superior to the rest this phenomenon could be also considered normal and natural.
We are usually considering our immediate group (friends, family) better than the others (which might also be part of our culture and ethnicity). Therefore, it is natural for people to consider that they are somehow better than the others, their group – better than other groups. Such a belief becomes pathological when it goes to an extreme. When one wishes for other groups not to exist and is ready to (or dreams of being ready, able) to eliminate the other groups.
