Yep.
Naive, simpletons, good intentioned people, whatever you want to call them, are the very ones most likely to become victimized by the Muslims they champion.
What was happening to him was caused by Islam, by Islamic xenophobia, hate and supremacism. These were good Muslims. The problem is that good Muslims, like good Nazis or good Communists, are terrible human beings.
What Does It Take for a Liberal Hostage to Lose His Illusions About Islam?
Daniel Greenfield, a Shillman Journalism Fellow at the Freedom Center, is a New York writer focusing on radical Islam. He is completing a book on the international challenges America faces in the 21st century.

Theo Padnos’ account of his time as a hostage is honestly told. This is a man who studied in a “religious academy”, who could quote verses from the Koran, who fell into a nightmare in which he discovered what Islam really was.
I began my studies in a neighborhood mosque, then enrolled in a religious school popular among those who dream of a “back to the days of the prophet” version of Islam. Later, I moved to Syria to study at a religious academy in Damascus
Somehow none of that alerted him to the difference between what Muslims believe and what liberals think they believe.
Padnos believed that the Free Syrian Army was some kind of resistance group, instead of another name for a bunch of Islamist militias with ties to Al Qaeda. He learned his mistake in the worst way possible.
… The leader — I’m not sure who it was, I couldn’t see — carried a heavy stick and a cattle prod. As I lay there, he hit me across the back of the head, then strolled around the room reciting prayers.
… During an interrogation session, the Kurd, who liked to be called Sheikh Kawa, nodded at a prisoner whose wrists were cuffed to a pipe just beneath the ceiling. His feet bicycled through the air. “You must let me down, for the sake of Allah! For the sake of Muhammad and Allah!” he screamed.
“This is our music!” Kawa yelled at me. “Do you hear it?”
… When religious authorities or higher-ranking Nusra Front members — anyone with bodyguards — came by my cell, I sometimes recited verses from the Quran. These were verses that I loved, and the visitors seemed pleased. But the net result of these recitations was . . . nothing. Eventually, one of the more educated guards explained to me that as a Christian and an American, I was his enemy. Islam compelled him to hate me.
“Does it really?” I asked…
Anyway, the Quran forbade amicable relations: “O you who believe!” this guard would recite. “Do not take the Jews and the Christians for friends. They are friends one to another. And whoso among you takes them for friends is indeed one of them.”

I listened to the fighters musing about their futures. “Hey, Abu Petra,” they asked me, “what is Sweden like?” If they were to present themselves as Syrian dissidents to the authorities, what would happen next? Was I familiar with the procedures in Sweden for seeking political asylum? And what about Berlin, supposing they found their way to Germany? How long would it take for them to learn German?
Yup. Some of these guys are coming to a place near you.
Fatah goons tried to make Oriana Fallaci into a human sacrifice. She went to a Fatah camp in Jordan in 1973, most likely full of sympathy for their Cause, then commonly called “the Palestinian revolution” or “the Palestinian Resistance” among the fashionable European “Left”. After the incident recounted at link, she learned better, although maybe not all at once:
