The quran expressly tells them to do that. Move into a new area and be nice to the people who live there. These people will think, oy, these muslim dudes are pretty cool. More and more of the locals become amicable towards islam and may even convert.
Then, the quran says, once you outnumber them, give them a choice, convert or die. And when they're all converted or dead ... move to the next area.
As for this Yahya person viocjit mentioned. Yahya is the Turkish equivalent of a televangelist, though he got his fortunes, not through television. He has a large following who hurl money at him by the truckload. This has allowed him to self-publish a ton of books. Most importantly, his atlas of creation, which is an utter farce as far as its contents go but which has been produced according to the highest standards. Top notch printing technology, highest quality paper, that sort of thing.
Then, using the truckloads of money, he started throwing hordes of lawyers at anyone critical of him or any of his books. He has even managed to get a bunch of websites blocked by the Turkish government.
Now there's something these Anonymous fellows might put some effort into. Anonymous has 'promised' to attack Belgium, sometime in early june because the Belgian government is blocking websites. Which websites? Dodgy gambling sites. Sooooo, anonymous is going to raise hell ... over a bunch of con artists' sites being blocked ... yeah ... that's ... splendid, I suppose
Why don't they, rather than support the Russian maffia, get off their arses, if they do want to make a point, and go after Turkey?
Now, if life were a movie, this post would instantly show up at the super-duper hightech fortress of Anonymous in Hawaii and the Head Anonymous would go ... By Crom, he's right!
