They are the ones doing the mutilation. Can blame them just like I can blame the baby killers. No real difference.
If you go to a number of,doctors who tell you not to do something, ignore them, and keep doctor shopping until you find doctors who will do what you want, that’s 100% on you. You were told the risks and advised to do something else and you didn’t listen.
If you read the story thats what the parents and kid did. They didnt stop until they finally found doctors who would go along with what they wanted to do, despite being told different information by other doctors. They didn’t drop it and wait a few years.
