Agree John Hardly - no room for patronising in multiculturalism, none for nostalgia either (except by choice in things like appreciating old music). No foisting, no imposing. Just acceptance of other cultures' existence next to ours (whatever "ours" is), learning the good things from each other, and avoiding the bad things.

I would argue that a culture that co-exists with others in such a way has a better chance of developing, through learning from others; while a culture that accepts only itself and does not give a hoot for others leads to an incestuous reinfocing of its own characteristics, good and bad, with reduced opportunities for development.
