Multiculturalism is the belief that all cultures are equal and no single culture is superior. It has spread around the world and is debated as either right or wrong. Supporters argue a multicultural society is wiser by incorporating diverse cultures, while opponents believe it could corrupt their own culture. Some politicians say multiculturalism is dead due to terrorist attacks proving their view that mixing cultures can have negative consequences, such as 9/11. The future of multiculturalism looks uncertain as it continues to decline in many places.
