What are monoculturalism and multiculturalism from a academic point of view?

A lot of people have been debating over the two terms through the lens of political agendas.

Monoculturalism according to wikipedia: "is the policy or process of supporting, advocating, or allowing the expression of the culture of a single social or ethnic group. It generally stems from beliefs within the dominant group that their cultural practices are superior to those of minority groups and is often related to the concept of ethnocentrism, which involves evaluating another culture based on the values and standards of one's own culture"

Multiculturalism according to wikipedia: "Multiculturalism is the coexistence of multiple cultures. In sociology and everyday usage, it is usually a synonym for ethnic or cultural pluralism in which various ethnic and cultural groups exist in a single society."

are these two terms actually polar opposite of each other or it's a venn diagram that has many overlapping areas?
