‘Female circumcision’, more properly female genital mutilation, is about repression of women, not the religion of Islam. It’d be untrue to say these specifically correlate: many Islam-practicing countries treat women comparatively well, and many non-Islamic countries are misogynist. It’s not mandatory in any country. However, some misogynistic cultures in Africa virtually force the mutilation: should a bride say no, she is mutilated in a more violent manner. It’s illegal and not practiced elsewhere, save for the odd case of immigrants here and there.
