A complex issue is already rising to the top here, and is very tightly interwoven with the question of infant circumcision: what rights should parents have over their children? That is to say, why are some of the opinion that a child is a blank piece of paper on which you can write anything you choose? What are the limits of a parent's right to make decisions for their child?
When we're talking about things like ideology, there is at least the advantage that the child can undo what they've been taught as they grow older.
But that's not the case with circumcision.
