Brother, you should change your views and become more sympathetic towards this and other actions that you may or may not find barbaric but were recommended and preferred by Rasoolullah . I know this is not the only issue you have with the Shafi'i madhhab, but you do realize that both the madhahib think positively of this "barbaric" activity. Female circumcision (I assume you're talking about this...) is from the sunnah but as has been mentioned before, the way this is carried out in many African countries is contrary to the sunnah. The form of circumcision performed in some African countries is the form that was practiced by non-Muslim Africans (and still is), where an entire organ is excised from the female genitalia. This is not permissible in Islam at all. Please seek clarification about what is meant by female circumcision from Shafi'i scholars.
