Response to a commenter about what Muslims believe
I disbelieve media analysis that these terrorists are somehow radicalized by visiting random ISIS websites. The radicalization comes from family and religious groups. The ISIS websites finish the process by urging radical beliefs be converted to radical actions.
As I am sure I explained before, Islam is a fundamentalist religion. All Muslims believe that the Koran is the true and literal word of God (Allah) and that Mohammed was the most perfect man and people should follow the examples he set. And the Hadiths and other sources about Mohammed’s life, although not the true and literal word of God, are nevertheless believe to tell the true story of Allah. Nearly all Muslims really really believe this and it’s what they are taught at Mosques and religious schools. There is no major branch of Islam that believes that the Koran should not be taken 100% literally. This is something that liberals (who don’t personally believe that there is any religious text that’s the true literal word of any divine beings) simply cannot understand.
However, Islam, like all other religions, historically existed—or was appropriated for the function—of serving the elites. Law and order benefits the elites, but people deciding on their own to commit jihad, that doesn’t benefit the elites, so that stuff was not taught to people. Most Muslims, like most Christians, non-Orthodox Jews, etc., are too lazy to read the Holy texts themselves and they let religious leaders tell them what they are supposed to do in order to be good Muslims.
However, since all Muslims have been primed to believe that the Koran is the true and literal word of God, and that Mohammed was the most perfect human and men should live by his example, they are extremely susceptible to groups like ISIS who teach what the Koran really says about jihad, and how Mohammed really lived. And based on the texts of the Koran and the Hadiths, ISIS is correct, or at least they have a very legitimately correct textually-based interpretation.
