The classification of people into groups who have little contact with each other is often the first step toward genocide. What are some of the actions societies can take to avoid this kind of classification?

The correct answer is:

In order to prevent the genocide, people must, first of all, understand that the world is composed of many countries of different cultures, beliefs, religions, plurality. The definition of right and wrong can vary, and these concepts can be reversed, depending on the culture of each country. To begin with, it is necessary to understand that respect must be used, above all else.

According to some studies, the best way to prevent this frist stage of genocide (classification) is developing universalistic institutions that transcend ethnic or racial divisions, promoting tolerance and understanding among the countries.
