Explain what is controversial about multiculturalism.

Multiculturalism is controversial because it challenges traditional notions of national identity and cultural homogeneity. Some people argue that multiculturalism can lead to social fragmentation and the erosion of national unity, as it encourages the preservation of distinct cultural identities within a society. Others believe that multiculturalism promotes diversity and inclusivity, and that it enriches society by allowing different cultures to coexist and interact. Additionally, there are concerns about the potential for cultural clashes and conflicts, as well as debates about the extent to which multiculturalism should be accommodated within existing social and political structures. Overall, the controversy surrounding multiculturalism stems from differing perspectives on the value of cultural diversity and the implications for social cohesion and national identity.
