Explanation:

1) Ethnocentrism is the belief one's race is superior to the other. It creates a divide in society based on the binary of "Us vs Them". Racism has been a part of colonial history that subjugates, discriminates and dominates over the people of a culture.

2) Post Colonialism racism/ethnocentrism has seen a gradual decline. However, the extent to which it should have diminished is far from reality. It could be due to the long prejudice in our minds towards people of particular community, gender, color or sex.

3) The recent outbreak of Corona Virus has led to huge discrimination against Asians as seen in different parts of the world.  

every society, in order to meet the needs of it's people, has to answer three basic questions:
