Personally, I think the government needs to butt out. These decisions should be left up to parents, providers (including psych/social work), and ultimately the patients themselves. As the article stated, these surgical procedures are so rarely done on young patients. Hormone regimens are reversible and could be an effective treatment for gender dysphoria, provided it's considered safe (psychologically and physiologically). Calling it child abuse is extreme, in my opinion: parents already consent to growth treatments, ADHD medications and other invasive therapies.
Of course, teens shouldn't be allowed free reign for these issues, but they're not allowed that for really any medical decision. Even something as common as birth control requires counseling, education and a prescription from a provider.
** as a note: the proper terminology is "transgender person/people", NOT "Transgenders". It's a descriptor; not a noun.
