You dislike division, yes? Multiculturalism is inherently divisive. That is a property of multiculturalism. It cannot be changed, for it is fact.
Simply stating somehting as a fact does not make it so. What is it that makes it devisive (?) - please show me an example so I can understand better.
Xenophobia is a natural reaction. However far people go to supress it, some are less successful than others. The more prevalent a society with multiple cultures and races is, the more likely that xenophobia will exist. You can't prevent it.
People are scared of what they do not understand. People do not understand other cultures due to the imaginary lines we have drawn on maps. With familiarity people become less scared. You can prevent it with ease - simply do not divide people along artificial means. Doing so makes Xenophobia worse when people come into contact with people different form themselves.
Capitalists like to paint it as a great philanthropic exercise, this influx of immigrants into Britain and Western Europe. The reality is that they are brought there for the sole purpose of being used as cheap labour, with little care for the consequences. The fact is that not only are minorities inherentely disadvantaged in most societies (that is a property of being a minority), but that they whine when they rise up and keep bringing them in because they're treated like shit. They are brought there almost exclusively to be treated like shit in the first place!
Or, alternativley, migrants move to the richer countries to work hard and make something of themselves. Free enterprise of that nature allowed the USA to become the most powerful nation on Earth. The NHS employs a huge number of overseas doctors and nurses, as without them the number of competent staff the UK alone could provide would be unable to provide nationalized medical care of the standard it does. I see little wrong with someone wanting to better thier circumstances - someone moving from eastern europe to the UK in a legal manner (it would be a different story if said immigration was illegal) to earn more than they would doing the same job at home seems a hard thing to berate someone for.
This goes especially for Third World immigration, but others too - strong positive net immigration from those countries has created many problems for society and led to brain drains disastrous for the economies. Case study: the Philippines.
Brain drain is a bad thing, I 100% agree, as the best and brightest are the ones most likley to move to make thier lives better. However, don't discount that a lot of people either send money home to family to support them, or eventually move back home with thier relative wealth to make a difference in thier home community. Granted, this is not the majority of cases, but it does happen.
The fact is that the native population tends to resent immigrants and people of another culture or race (love it or hate it, race is strongly tied to culture), and many immigrants dislike where they live or would prefer to be in their homeland. This leads both parties into a common ruin.
Again, this is simply a product of those imaginary lines we ike to draw on the ground. More familiarity = less fear.
The problem with people like Solifuge is that they are not realistic
The reality of the world is that it is now a small place, with people, ideas and information free to move (for the most part) pretty much where they please. We need to be able to cope with this free movement, not restrict it. Bigotry is bred in homogenus groups, not diverse ones.
