OK then we see things very similarly when it comes to abortion ... it's unfortunate but if a woman feels it is necessary, for WHATEVER reason, then it's OK up to a certain limit. As Ann Furedi puts it in the OP link: ‘We either support women’s capacity to decide, or we don’t ... You can’t be pro-choice except when you don’t like the choice, because that’s not pro-choice at all.’
To take things a little further, if we're sufficiently liberal that we allow mothers-to-be to be pro-choice about the life of their unborn child, based on for example (again from the OP link) "‘her family will disown her and she’ll lose her home, her husband whom she loves, and her existing children", then surely the exact same thinking can apply to other choices made about the health and wellbeing of a child that is allowed to be born and raised in a warm and loving, albeit religious, environment - choices about whether or not to circumcise, for example.
To me, denying the right to life is worse than denying the right to a foreskin, but I accept that both take place in the world we're living in and other religions, cultures or worldviews are quite comfortable with it. As long as their choices don't affect my choices then I can live with that.
