PREVALENCE
Female circumcision is currently practiced in at least 28 countries stretching across the center of Africa north of the equator; it is not found in southern Africa or in the Arabic-speaking nations of North Africa, with the exception of Egypt.6 Female circumcision occurs among Muslims, Christians, animists and one Jewish sect, although no religion requires it.*
Mohammed addressed the issue of genital mutilation, permitting but not mandating the practice.
Do you seriously want to make the case that this is a Christian or even a Jewish practice? What sort of equivalency are you drawing?
