As america's population expanded, tensions between citizens began to increase and american culture divided into three sections. (1) what was this called and (2) why did this happen?

Having lost the external enemy - the former USSR - the USA lost the factor that united the nation and shaped its common interests. Having lost the image of an external enemy, the Americans began to look for an internal enemy. As a result, a “war of cultures” arose in the country: feminists began to denounce the dominant position of men in the modern world, ethnic minorities opposed WASP (white, Anglo-Saxons, Protestants), and the colored population opposed white.

In the last third of the 20th century, two trends retained their influence, and the share of the radical tendency began to increase towards the end of the century. It was expressed by several organizations, the most famous of which was the "Nation of Islam" led by L. Farrakhan. Farrakhan and his supporters contributed to the extremist black nationalism. The belief was spread among many black Americans that integrating into white America was possible only by self-transforming in the likeness of whites, i.e., at the cost of giving up one's own sociocultural identity.

Rejection of such a 'price' was reflected in the multicultural ideology, which has gained strength (equality and diversity of racial-ethnic cultures). This ideology, proving that all racial-ethnic cultures are self-valuable and equal, and not one of them, including the culture of whites, can be placed and valued above others, had a democratic sound. Many American politicians and ideologists tried to present the theory of multiculturalism as a new manifestation of the true pluralism and democracy of American society. But this statement hid the very important fact that this theory of multiculturalism reflected a radical protest against the dominance of white culture and included a 'virus' and the threat of disintegration of American society along racial and ethnic lines. The shrewd white politicians have recognized this danger. Clinton, recognizing that in the United States at the end of the 20th century there was a revival of hidden segregation and that racism, rooted in the law, remained in the minds of white Americans, was anxious about the spread of multiculturalism. Its flip side, he noted, was the deepening division of races and ethnic groups. The US President considered it necessary to formulate the "American dream" as an 'antidote,' which would unite and hold together all the races and ethnic groups of the country. But as world historical experience testifies, it is practically impossible to formulate and bring to mind such an idea from above, if it is not accepted by the majority of the population.

In addition, the program and ideology of feminism split American society. The number of Americans, both women and men, who shared the principles of feminism, was constantly growing.
