I think it's just human nature that we identify most with people that are like us, so the multicultural society will never work. People are never going to live in a society full of different cultures that actually integrate with each other while at the same time keeping their cultural distinctiveness.

One of two things will happen. Either the minority culture will be gradually assimilated into that of the majority, or there will keep their separate ways and relations will continue to deteriorate.

Whether or not they can be assimilated depends on how similar they are. Culture might be the main factor, but in reality I suspect skin tone really does make a big difference on a subconcious level.

And even then the cultural compatablity is more complex that you might think. For example, why do Indian's integrate OK, but no Arabs?

Also, Meneldil, on that point you made regarding Qeuebecers rejecting multi-culturalism, I'm not sure how true that is. Certainly it was in the past, but even since their Quiet Revolution back in the 60's they've been going the for the soppy civic 'everyone that lives in x is nationality x' type approach, much the same way as Scottish nationalist have.
