We (in Britain, at least) are constantly told that multi-culturalism is a good thing. Now, I would have no problem with that, if only it could explain to me why. Millions, if not thousands of millions of public money is spent on schemes promoting the concept of multi-culturalism (not that this does anything, though, except perhaps make some already liberally-minded people violently anti-racist).
I do not see an advantage in it, since it dilutes our own culture, and makes people feel extraordinarily and unreasonably guilty for the Empire.
I believe, that while keeping some of their own culture, immigrants should generally integrate with the nation that they are moving to, and that the nation should not adapt itself too much for the immigrants.

What do the Orgahs (which seems to be the commonly accepted term for the subjects of TosaInu) think of multi-culturalism?
