Multiculturalism is when a country or community has people from different cultures and backgrounds living in it together. Sometimes, people criticize multiculturalism because they think it is hard to make everyone accept and respect everyone's cultures. This can cause tension between different groups of people living together. It can also be difficult for people to adjust to living near each other when their cultures are so different. Additionally, some people dislike multiculturalism because they think it could lead to the fading away of a country's own culture and traditions.
