Multiculturalism

Considering the problems it has been shown to cause, is it worth it?

In b4 racists, stormfags and anyone with a prejudiced opinion and little else.

Multiculturalism is tolerable as long as it doesn't start displacing the native culture.  Notice how no one complains when their country isn't being swamped with foreigners.  English-speaking countries just take the whole politically correct thing too far.
