Answer:
The answer is ethnocentrism.
Explanation:
Ethnocentrism is defined as the idea that one's own culture is superior to others, especially regarding aspects such as culture, language and customs.
The phenomenon is believed to be a learned behaviour. It can be explained because a person that has resided in a certain country or area for a long time has probably acquired its predominant values and ideas. This is called acculturation.
Ethnocentism in the extreme can lead to hostile attitudes towards out-groups and discrimination.
