Being Ethnocentric means judging other peoples culture, beliefs, values and general way of life based on the standard of one's origin or culture, seeing one's origin has being superior or better when compared to that of others. Being ethnocentric could lead to division amidst of various people that are of different religion, race, and ethnic groups, such belief makes people see themselves as being better off than others who are not of the same origin with them. This is a pure display of racism and prejudice.
