In a perfect world the needless mutilation of children would not happen. Infant circumcision is wrong, period, just as it is wrong for parents to cut of a baby's finger. It is mutilation, and it is a form of abuse. It should be illegal, and should carry the sort of gaol sentence that - for example - cutting off a baby's finger would.
Religion does not make it acceptable. Many Jewish communities are moving away from circumsision, particularly in the UK. Thank God!
Soietal norms in the US do not make it acceptable there. It is a barbaric practice, and there needs to be a proper lobby in the US to make people realise that is wrong and get legal change.
If you are cut and happy with it, or make this choice as an adult, great. If it is needed for medical reasons, fine. But these are different issues - lets be clear that mutilation of babies for any reason whatsoever is wrong.
