I spent three years in Turkey.
What I've observed is that the more religious Muslims were far more likely to be utter jerks than those who were "cultural Muslims."
The Turks are VERY different from the Arabs. I knew only ONE Turk, who also was working for ARAMCO. He was the NICEST guy in the world.
My husband and I visited Turkey. We enjoyed it, but we were TOURISTS and didn't have to live there.
The YOUNG men are the WORST, I think, because some of them are fanatics. Fanatics, of any ilk, are obnoxious.
Islam spread by the sword.
Christianity spread by THE WORD.
THAT says it all.
