In those cases, the state must show a “compelling interest” to overturn a religious objection. It’s hard to see what compelling interest an incorporation of the State of California has in this matter.
Really? No compelling state interest? People are performing a painful and unnecessary surgical procedure on infants, without their consent, affecting them for the rest of their lives, for superstitious and aesthetic (i.e. self-centered) reasons. The state always has an interest in protecting children from abuse. That will be the argument, and I’m not sure I disagree with it.
That said, I wouldn’t support a ban like this. It should be a family decision. But I really don’t think non-Jewish parents (for instance) should consider it the “default” (the “health reasons” are bullshit in a first world country), or that a father should decide to circumcise just because he was.
