I'll tell you why. Immigration is the ultimate weapon that will allow the left, both in Europe and in the USA, to destroy Western Culture.
The Left is trying to dismantle the bases for traditional social cohesion--in effect, depriving the intended subject populations of any basis to work together effectively to strike back. A homogenious population group, proud of their heritage, are a real threat to those who pursue a Collectivist, conformist, world order.
If you look at what is accepted in terms of group identification, and what is not, you will see over and over again--both in America and in Europe--the same pattern. A grouping of people with a sense of grievance--i.e. people looking to the Government to make things right--is acceptable. A grouping of people with a Conservative tradition, who want to be left alone, is not.
The Nationalist, who loves his own country and his own kith and kin, has no place in their new world order. He is a threat. The major reason for encouraging liberal immigration, is really to emasculate such people. You are close to being on ground zero of the real battle, when you take them on on this issue (immigration). (See, also, An American Immigration Policy, and Myths & Myth Makers In American "Higher" Education. With those articles, you will find links to a lot of others that explore different nuances of the same battle.)

Your point is well taken, but there's another rationale (besides the ideological "diversity is our strength" myth) for uncontrolled immigration from Third World countries into Europe that I see constantly cited, and that is that, as the populations of Europe (i.e., the original Europeans, ethnic Europeans, white people, whatever term is politically correct these days) fail to reproduce at replacement levels, and as the demographic contour of their societies shifts to a more and more elderly profile, high levels of immigration are purportedly "necessary" to maintain economic growth, a labor pool, and a tax base to ensure continuation of the colossally expensive welfare states Western European nations have. (We're starting to see the same arguments here in defense of uncontrolled immigration, by the way).
It boils down to yet another version of "It's the Economy, Stupid."
The left always killed political opponents, just ask people in Prague or former East-Germany.
It is time for the world to see that democracy, freedom of speech and the left are not compatible.
I will still vote for Fortuyn! No one will take that away from me.
