I agree with the consent argument. Because circumcision is a medically pointless (at best) procedure that is permanent and irreversible. Vaccines and medicines not only have a clear medical benefit with little-to-no downsides, they are generally not permanent.

I'm all for children's rights and I'm definitely against things like piercing infants' ears. But as a parent you do have to make a lot of "nonconsensual" decisions for babies because they cannot make any decisions themselves. The difference is there's a clear benefit. When my kid is screaming with an earache technically me giving them ibuprofen is nonconsensual, but it's obvious why I'm doing it.
