Me neither. And that's the crux for me.
So, stepping aside from the issue of consent, here's how I would improve the situation based on what I've read and learned as part of this thread.
Responding to the safety concerns in the OP, Mohels need to be regulated and licensed per state in a similar manner as Drs and Dentists. An American needs a license to drive a car safely, it makes sense to require a license for individuals who make permanent changes to a child's body. Tattoo artists need a license in most states. Hair stylists, I think, need a license. Yes, it's a hassle and Mohels will hate it, but, at this point, it probably makes sense for government t get involved because children are being harmed.
Also, many Mohels travel over a large area and I think it would be better for Mohels to remain local. Adding a licensing requirement that is localized by state would help to encourage that. The Mohel we used lives here in town, is a member of the community, and I felt much more at ease knowing his reputation and that he would be checking in on my son and that he would be accountable if there was trouble.
Going back to consent, I think it would be good for parents to accept some ( if not all ) legal liability for emotional and physical damages to the child as a result of the choice to circumcise their child without consent. Some sort of waiver which clearly states that the parent believes what they are doing is in the best interests of the child, but that ultimately the child will decide later if the parent made the correct choice. If the parent makes the wrong choice, there should be consequences. The intention is to reduce or eliminate casual circumcisions that have nothing to do with religious belief. I honestly think that many modern Jewish people would balk at signing a waiver like this and would seriously reconsider making a permanent change to their child under these circumstances.
It's not a perfect solution, but it's something. I acknowledge that many children's human rights are not being protected, and I think reducing that number is a good idea. The compromise is that that religious parents would get a *temporary* exception made for this one specific procedure. It's not perfect, but, maybe it would do some good.
