Owing to the sway of political correctness, multiculturalism has been caught in an awkward situation ever since it burgeons in the second half of the 20^(th) century. It has fallen victim to the myth of what I call a monolith theory, and that of an umbrella theory at the same time. Monolithic theory, which incorporates an ethnic essentialism, has led to the ethnocentric petition for collective rights and the consequent stagnation of cultural development. As for the umbrella theory, too much inclusion of subjugated and/or subordinated groups has caused problems such as misconstruction of cultural minorities, swell of gender consciousness, and ignorance of class effects. In view of the fact that social justice is the main concern of both camps, this article suggests that they try to reach a mutual understanding on the basis of this common goal, and then go on to reconsider the inter-relationships among ethnicity, class, gender and the various forms of social oppression in an open and multidimensional context.
