Multiculturalism has its supporters and critics alike. Its supporters often see it as a self-evident entitlement of cultural groups, as a form of civil rights grounded in equality of cultures. They often assume it will lead to interculturalism - beneficial cultural exchanges, where cultures learn about each other's literature, art and philosophy ( high culture), and influence each other's music, fashion and cuisine. Its opponents often see it as something which has been imposed on them without their consent. As multiculturalism as an official policy is almost exclusively limited to Western countries, some in the West view multiculturalism as an assault upon the foundations of Western civilization. Opponents of multiculturalism see it as inherently divisive and fear it will lead to cultural ghettos, undermining national unity. In Europe especially, opponents see multiculturalism as a direct assault on the national identity, and on the nation itself, and sometimes as a conspiracy to Islamise Europe.
