Its both 'religious' and cultural.
First, the 'religious' part. islam is NOT a religion, its a militaristic political construct designed to subjugate those it conquers. Its entire history instructs us so. What we are seeing today is the identical behavior of the "prophet' and his followers. Its all on tape. It isn't arguable. The most charitable description of the drooling demoniac they call their 'prophet' is marauder, and at that, he was the most prolific in history. Among the problems with islam is that its adherents view it as a 'religion' rather than the mafia that it as. Ergo the fervor.
Second, islam descends from those who descend from Ishmael, one of Abraham's sons.
Scripture says "He will be a wild donkey of a man; his hand will be against everyone and everyone's hand against him, and he will live in hostility toward all his brothers." That describes the descendants and their, er, 'culture' to a 'T'.
Ishmael was walking, breathing violence. It would follow that his descendants would be violent.
Enter the 'prophet'. Rather than drone on with documented accounts of mo's child beating, wife beating, murderous, plunderous, rapist, polygamist, pedophiliac, necrophiliac, bestial history, suffice to say that mo came from polytheists that had a 'god' for every day of the year - his village's fave being 'allah', the moon god - ergo the crescent on everything. Evidently, mo spent a whole month one night is a cave, he believed, with the angel Gabriel, and emerged with a vision he believed he was to impart to the world. He bounced it off the local Jews. They panned it. Tried it on local Christians. They passed. Ergo the hate and hostility toward these. mo, being the descendant of walking, breathing violence took his wrath out on the locals who had dissed him, and then turned hissef loose on the rest of the world. 'Followers' then were as easy to recruit as they are today - 'kill, rape, maim, and loot with impunity, and death will greet you with 72 virgins'. The message appeals to young 'men' of low self esteem.
A couple of points that elude the 'media' need to be made. First, the world of islam is desperately inbred. If you're interested,
this explains in detail. Second, the incidence of violence in the muslim world escalates with muslim population growth. Again,
the numbers, if you're interested. These people cannot escape who they are. Even if they could, they are bound by islam which they can only escape by death. It isn't reasonable to expect such creatures to be transplanted into Western 'democracies' and assimilate. Oh, and they breed like crazed rabbits.
mo referred to his outward 'migrations' as 'Hijrah'. Hijrah is what happened to the Arabian peninsula, the Mideast, Africa, much of Asia, and large chunks of Europe until those evil, barbaric Crusaders pushed back. Otherwise we'd all be inbred savages like mo's descendants. But wait, '
Hijrah' is alive and well and overrunning Europe as we speak.
Here's the forecast...
One might reasonably ask 'why we are being subjected to this suicidal insanity'. A clue might be found in our 'president's' insistence on being called "Barack Hussein Obama".
