Multiculturalism

Definition:
1. the policy or practice of giving equal attention or representation to the cultural needs and contributions of all the groups in a society: special emphasis may be given to minority groups underrepresented in the past, as through bilingual education.

2. the policy of maintaining a diversity of ethnic cultures within a community. (source: http://dictionary.reference.com/browse/multiculturalism)
Explanation:
In my own words I think multiculturalism means to allow people to practice their own culture. The religion a person chooses should be free of choice and the groups in society should support the culture and they get treated equally. Also social and educational programs should encourage interest in many types of cultures and societies not just one main culture.
Metaphor:

Multiculturalism is like a pot of soup. You add all the vegetables etc and mix it together which is like adding all the cultures and mixing them in society and it turns out really good because of the variety of different vegetables. In society it is better with a mix of cultures because it is not just one set culture there is variety.
