I just watched the video.
What will the world be like in 30 years if these projections are accurate?
Well, I'm not sure if they are accurate at all because they are misrepresenting Islam as inherently antagonistic, so I'm concerned about the neutrality of the assertion.
But hypothetically, if 30 years from now, Europe does become a predominantly Muslim continent (which I highly doubt), it won't be like an Orwellian state, a la, Taliban rule in Afghanistan and it boggles me where imagination takes people sometimes. Such a drastic change is highly improbable considering how most of Western Europe is politically stable whereas Afghanistan -- after 2 decades of civil war -- is
still not. If there
is a change, it will be subtle and gradual and it will be evolutionary rather than revolutionary.
An insane assumption many people make is that the 'Muslim World' is separate from 'The West'. It's not. The 'Muslim World' is identical to the West inasmuch as the sexual taboos and poverty allow us to be. At its core (considering how we are exposed to similar cultural memes in our lives, thanks to global connectivity), they are essentially the same. Sure, you get the occasional demonization (similar to how this video is doing), but given how many Muslims operate on Western-made devices/memes in their daily lives, it doesn't make sense that we can be so culturally different. We watch all your movies and listen to all the same songs. We have iPhones and hipster glasses and indie music and facebook. The newest rage here is 3D cinema. It's the same, except less rich, more lower class, and more sexually conservative - and these differences are regional. [I hate saying 'we', but somehow it fits.]
Anyway, the point being, an Islamic society is not necessarily regressive. Moderation can exist, like in many Muslim countries at present.
If Islam is applied throughout Europe, I reckon it will only mildly change the culture by making it slightly more conservative, however I doubt any of their luxuries are being taken away any time soon. It won't make any drastic difference and any fear of such is rooted in racism/xenophobia.
Of course, I'm theorizing.
Also of note, I'm
deeply irreligious and anything I say here is purely mental masturbation. I don't wish to see
any religion take over the world.
Or... do you think that Islam is a strong enough religious culture to maintain itself in the face of all that Western Civilization can offer to distract it...
No, I don't think so, and Islam is not a culture. This will be apparent to you when you compare the Muslims from, I don't know, China, to Turkey, and then Afghanistan.
Most importantly, what if Islam regains its former "convert or die" approach once Muslims get into "power" in these nations?
And disregard 1500 years of cultural evolution? Highly improbable.
