As I said...Muslims...cultural or religious was not the point.
"Debate Among Muslims:
As noted above, FGM is a social custom, not a religious practice. However, in those Muslim countries where it is practice, FGM is often justified by two controversial sayings of the Prophet Mohammed that seem to favor sunna circumcision. The authenticity of these sayings are unconfirmed, and some scholars have refuted them. Even if true, they only permit the practice; they do not mandate it."
