Cutting off a baby's boys foreskin is cruel and unless there are strong medical reasons it should be outlawed. Babies feel pain and sometimes circumcisms can go wrong.
There should be limits to what people do in the name of religion. Child abuse should not be allowed just becauase it is not PC to upset ethnic minorities. If an adult choses to be circumised for religious reasons with no pain relief then that is their decision.
The use of corporal punishment is heavily restricted in the UK. Infact there are many people think there should be a total ban on smacking. It is illogical not to campaign for a ban on the circumicising of little boys.
