I don't think anyone who has looked into getting a CI thinks there's not surgery involved, I haven't seen anyone arguing that it's some kind of topical ointment or anything.
Is your argument with the idea that a parent would intervene in how a child would access language or is it just with allowing medical treatment for a child. Do you object to all other invasive medical processes such as vaccinations, prescription medicine, filling cavities, circumcision, removing tonsils, removing wisdom teeth, inserting ear tubes or is there some line of demarcation?
