COMMENT ABOUT MULTICULTURALISM: GOOD, BAD OR BOTH?

When we talk about multicultulasim, we are talking about different races, religions, foods, color of skin, and many things more together. I think that many races living together are good because we can learn some good things about other cultures, or the others persons of the other culture can learn good things about us. 
One of the good things that we can apreciate of having person from other contries, is that they introduce their costums in our country, for example: when chinese people have a restaurant.
