The Associated Press published a report on Monday, compiled from court testimony and interviews with former ISIS fighters, that painted a dim picture of the Islamic State’s recruits. The early waves, in particular, were so clueless that some of them had to order Islam for Dummies from Amazon.com to brush up on the religion.

That juicy little tidbit is, naturally, the basis for the AP’s headline: “Islam For Dummies: IS Recruits Have Poor Grasp of Faith.” However, only two recruits from Britain were that unclear about the concept of jihad. 70 percent of early recruits claimed to have “basic” knowledge of sharia law, while 24 percent described themselves as “intermediate” students of the Islamic legal code, and 5 percent “advanced.” This would suggest only one percent of the people ISIS roped in were largely ignorant of sharia law.

The takeaway from the Associated Press report is not that Islamic State recruits were broadly unfamiliar with Islam — it is that they knew just enough about “moderate Islam” to fall prey to the Islamic State’s appeal.

ISIS radicalizes young Muslims by telling them, in essence, the Islam you get from your parents, and the imam at the mosque you scarcely bother to attend, isn’t the real deal. We are the champions of authentic Islam. Here’s what the moderates don’t want you to hear from the Koran.

This message is mixed with appeals to factional and national solidarity. For example, the AP spoke with a European recruit who “thought he was joining a group to fight President Bashar Assad and help Syrians, not the Islamic State.” He ended up packed into a safe house with other recruits while ISIS imams indoctrinated them.

The Associated Press concludes this means ISIS preys on “religious ignorance, allowing extremists to impose a brand of Islam constructed to suit its goal of maximum territorial expansion and carnage as soon as recruits come under its sway.”

It would be equally valid to describe this as religious curiosity, added to the sense of alienation and frustration that drives so many radicals, violent or otherwise. There seems to be little evidence that would suggest intensive study of Islam halts or reverses the radicalization process — in fact, there is a dismaying shortage of evidence that ISIS recruits can be talked out of radicalization, once it passes a certain point.

The constant refrain from the families of Islamic State recruits and “lone wolf” jihadis is surprise: no one in the family ever seemed to realize just how far gone their ISIS-supporting child was until it was too late. One of the reasons radicalization seems so puzzling and sudden to experts is that such denials are accepted at face value.

Only later do we learn that the jihadi held radical beliefs for much longer than the press was originally led to believe, or the jihadi had a history of run-ins with the law. Alternatively, the families of Western jihadis may be missing important signs of radicalization because they have been taught not to see them, by the media/government that insists terrorism has absolutely nothing whatsoever to do with Islam.

For example, the AP report quotes ISIS recruit Karim Mohammad-Aggad, who journeyed to the Islamic State in Syria with his brother and a group of friends after an Islamic State recruiter contacted them in Germany, claiming he was bamboozled with “smooth talk” from the recruiter.

“My religious beliefs had nothing to do with my departure. Islam was used to trap me like a wolf,” he said in court, insisting he didn’t “have the knowledge” to answer questions about sharia. A co-defendant gave the same answer, and the Associated Press points out that both Karim and his brother Foued said they had only “basic” knowledge of sharia when they filled out the ISIS entry questionnaire.

Those statements are a very thin reed to hang the “ISIS recruits don’t know anything about Islam” argument upon, especially since Karim’s little brother Foued was one of the monsters who carried out the unspeakable atrocity at the Bataclan nightclub in Paris last November.

Another assertion in the AP report, made by a study from the U.S. military’s Combating Terrorism Center, is that ISIS recruits who claimed advanced knowledge of sharia were less likely to volunteer for suicide missions.

“If martyrdom is seen as the highest religious calling, then a reasonable expectation would be that the people with the most knowledge about Islamic law (Shariah) would desire to carry out these operations with greater frequency,” said the Combating Terrorism Center report. However, “those with the most religious knowledge within the organization itself are the least likely to volunteer to be suicide bombers.”

That is a difficult assertion to evaluate without knowing a great deal more about the backgrounds of the individuals in question. A very small group, since as the AP noted, only 5 percent of incoming Islamic State fighters claimed to have “advanced” knowledge of sharia on the entry paperwork. Broad conclusions cannot be drawn from the way a tiny fraction of ISIS recruits described themselves. They might not have wanted to go on suicide missions, but they were still willing to fight for the Islamic State.

Also, sharia law does not require suicide bombing. There is an argument among Muslim scholars about whether sharia forbids suicide, or murder, but the Koran repeatedly encourages courageous battle against infidels, with a willingness to kill or die in the effort. It is a mistake to confuse sharia law with the totality of Islamic belief and tradition, as practiced by many different groups across an enormous worldwide population.

“Sharia forbids suicide, so suicide bombers don’t understand sharia” is a variation on the No True Muslim fallacy, a tautology which argues terrorists can’t possibly understand authentic Islam because no one who practices authentic Islam would be a terrorist.

The ultimate ends of such an argument — a reformation of Islam in which violence is expunged from the religion, and assimilation-minded moderates triumph in all of Islam’s many factions — is highly desirable. The question is how to get there, and ignoring or downplaying the importance of Islam in the appeal made by ISIS and other extremist groups is not likely to help either moderate Muslims or secular governments devise an effective strategy for combating the radicals.

History renders a grim verdict on that approach: the Western world has been pushing No True Muslim arguments with all of its might, especially after the 9/11 attacks, and yet ISIS happened. The young Western recruits described in the Associated Press report spent their entire lives in the “Religion of Peace”/”Terrorists are on the Wrong Side of History” era, but they still ended up fighting for the Islamic State in Syria. What they tell courts today, as they fight for reduced sentences, is very different than what they probably would have said when they first arrived in the “caliphate.”

Former CIA case officer Patrick Skinner told the Associated Press that most ISIS recruits are “reaching for a sense of belonging, a sense of notoriety, a sense of excitement,” and he claimed, “religion is an afterthought.” If that’s true, then why is the Islamic State so much more successful than the many other groups that offer disaffected youngsters a sense of belonging, notoriety, and excitement? Falling in with a local gang is easy; abandoning your family, and evading the law enforcement agencies of several nations, to join ISIS in Syria or Iraq is hard.

The Islamic State’s religious appeal may be only one ingredient in the fuel that drives people to make that awful choice, but discounting it as irrelevant is dangerous.
