The world needs to follow Sweden's example and forbid FGM. I hope the UN will rule that FGM is harmful to quality of life and is a barbaric practice that should be eradicated.
I think people should take the attitude, " I don't care what the old scriptures say. We can make rulings from first principles based on the desire to maximize well being and minimize suffering, like Sam Harris talks about"
The great thing about English common law is that it is based on precedent and can evolve. People need to focus on what current laws like English common law say, and play according to them. The scripture laws are out of date and irrelevant.
If Islam had any worth is would have ruled against FGM but it is stuck with an idea that the text is unchangeable.
Even the Bible has verses against circumcision. Galations chpt 5 is vaguely against circumcision, Gal 5v6, "For in Christ neither circumcision nor uncircumcision has any value. The only thing that counts is faith expressing itself in love"
Ephesians 5v28, "In this same way, husbands ought to love their wives as their own bodies. After all no one ever hated his body, but he feeds and cares for it"
Galations 5v13-24 is a get out clause from O.T. laws & regulations because it introduces ambiguity about whether the christian is free from O.T. laws or not. It sort of says to be guided by the consideration of whether the action is helpful to others or whether it is harmful, whether it is loving your neighbour as yourself or not.
