You can say the same thing about the Bible.
Fact of the matter is, Jews and Muslims lived side by side in the same cities for many years, however long ago all that shit was with the wars in the middle east and territories changing hands.
Its the people like the Wahabiasts that started perverting the shit all around and making it a hundred times more worse than it ever needed to be.
The fact that these people come from cultures that still adhere to primitive notions like Tribal laws & identity does not help and is the number one reason they are so barbaric.
They bitch & moan about how the Middle East was the cradel of modern culture and civilization, mathematics, philosophy, public engineering.. They were said to have electricity before the rest of the world caught up (whether that is before or after Edison and they were simply quick to adopt I can't say).
Hell, what looked like ancient battery systems were found in Iraq (or somewhere in that area).. All this shit. But because of their backwards social development, tribal systems & laws.. They have refused to step into the future. They are only modern in the sense of technology these days.
It's sad... pathetic really. Such a great people could contribute something like the decimal system, influence modern alphabets, and they are reduced to nothing but warring savages in the name of "god", because of a few fucked in the head religious people with a death grip on their countries.
