I guess that once Europeans will really start to realize and feel that they have become a minority, they will protect themselves much more against the immigrant groups, in the same way Muslims are doing it right now. So instead of becoming extinct, I imagine a scenario which is similiar to Brazil (or former South Africa), in which a rather tiny and highly protected elite of fully European ancestry will rule over mostly non-European nations. The sad glory for our children and descendants will be the side effect of probably having much higher career chances and earnings than we have now.
I haven't replied much in this thread because to be honest, it reeks with paranoia and fearmongering. A lot of this is based on the premise that "if the current trend continues", and frankly, I don't see
how it can continue, at least for a prolonged time which is essentially the sine-qua-non of these scenarios. There's a number of reasons why and how it cannot happen:
The first and most obvious is that birth rates world-wide are dropping, and have been dropping consistently for the past few decades, especially for countries with traditionally very high birth rates (most notably the Middle East). As a positive side effect of this population projections of the past had to be consistently projected downward. Populations will still continue to grow in most of these countries for many decades because there is still a surplus of young people. This actually very consistently reflects the developments that we saw historically in the West: birth rates began to drop in the 1960s, but western nations didn't feel the heat of a surplus of elderly until the 1980s or 1990s.
You might ask, why is this happening? It clearly cannot be exclusively due to Western lifestyles because this is also a phenomenon/trend that is happening in countries that are hardly to minimally westernized and where female emancipation is heavily frowned upon. In my opinion, the primary reason is urbanization, and the fact that the traditional large family model is non-sustainable in long-term within an urban environment. The costs of living are increasing considerably so even if people don't live in affluence, there are factors that drive people to have fewer children.
So where does this leave us in the future? Radical ideologies like Islamic fundamentalism (or, to pick historic examples, communism, or the Nazis) are primarily based around a large number of young (teens and early twenties), poorly-educated followners that have malleable minds and that can be easily indoctrinated for such ideologies to become zealous fanatics for the respective course. People in their 30s and 40s are much less likely to follow such ideologies so it's very likely that once the average age increases, I think that support for Islamic fundamentalism will vanish. Another aspect is that it is an ideology that offers no future. Well, it offers the prospect of a rosy afterlife for it's followners, but here and no, it's an ideology without any solutions for real life problems. It doesn't solve social or environmental problems. This is why I believe that radical Islam will eventually disappear on it's own. Not tomorrow, not in ten years, but eventually.
Apart from that, I'd like to point out something entire else: people in this thread have been talking about anonymous, homogenic mass that they address as "Muslims", which in fact are not a monolithic block, but are fractured by ethnic, linguistic, sectarian and social divides in any country on this planet. In particular, what about Albania and Bosnia? These are two European countries with substantial percentage of their population Muslims. Why do they fall off the rug?
Somebody also brought up the buzzword "Clash of Civilizations". What Samuel Huntington did in his "Clash of Civilizations" was that he draw lines which existed only in his mind onto a map. The worst thing that we can do is that we buy them and take his book as a blueprint for the next world war. In my opinion, Islam
by itself does not pose a threat to Western civilization. Note that I'm neither apologetic of Islam nor blue-eyed on the issue: radical Islam (or, more accurately,
violence-endorsing Islam, because that's the real problem) is much more a problem for the Islamic world itself than for the West. In my opinion, at the bottom line, Islam is just as much an intolerant, women-discriminating and violence-endorsing religion as Judaism and Christianity (if you don't want to believe that, I recommend reading the bible!). You get a very good idea when you listen to what Christian fundamentalists in the United States who use the First Ammendment as a blanc cheque for hate speech and for attempting to force their views on abortion, homosexuality and education upon the entire country.
So, I'd hereby like to ask everybody in this thread to stop the fear mongering and paranoia, the generalizations and stereotypes and start reading between the lines.
