I don’t have the answers, but I sure have a lot of questions.
Should all pupils in Germany’s state schools get educated in the tenets of Islam? If so, what version of Islam is the correct one that schoolchildren must internalize? Sunni Islam? Shiite Islam? Salafi Islam? Wahhabi Islam? Ahmadiyya Islam? Sunni Islam alone has five main sub-sects (Hanafi, Maliki, Shafi’i, Hanbalites, and Ẓāhirī), and all those f(r)actions have splinters. Who will decide, for the purposes of German schools, what the proper theology is?
