Is there a ban on circumcision? Is there anything close? Anyway...
I would imagine it would be classed as a religious practice so it wouldn't need to go to privacy grounds.
But, let's pretend it's no longer a religious thing so the next step WOULD be seeing if falls under privacy. Then it comes back to the Roe decision. The privacy is temporary, and you start losing it when hurting another entity.
So, most medical treatments don't hurt other people
Circumcision ONLY hurts a person. It should be banned for parents to do to their kids.
Abortion hurts another entity at a certain number of weeks with disagreement on that number. Remember, Roe was a Pro-Life and Anti-Choice decision. You were allowed privacy for your decision until a certain number of weeks (it changed over time)
Now, ADULT circumcision shouldn't be banned. If that's your religious choice as an adult, that's fine. All privacy to you.
But parents fucking around with children's genitalia is hurting someone else... you know just like gender transitions where it's illegal for parents to do anything with a child's genitalia. Similarly, putting your child into gay conversion therapy, even though is utter nonsense and tends to just prolong the inevitable, should be allowed until it starts hurting people. Unfortunately, it's mostly torture. Thus probably should be banned until 18 and if you decide on doing it yourself, so be jt
