This is fundamentally wrong as it infringes on the right of parents to decide what is best for their child, that includes what faith it will be taught.
Either there is freedom of religion or there isn't, and banning this is banning a central part of Jewish faith, it is a rite of passage for them.
Still, nothing like having a pop at people's beliefs if they don't match yours.
There's a difference from teaching your children beliefs (which are reversible) and altering their body which is irreversible.
I think it's really infringing the rights of the child as he has no say in the matter at all and it should be left for him to decide when he is older.
