Truth,
"Explain, if you can, why a cis teen can get breast reduction surgery and a trans teen cannot.
Explain, if you can, why a cis teen can get puberty blockers, but a trans teen cannot.
Explain, if you can, why a cis teen can get hormone replacement therapy, but a trans teen cannot."
Because the issue isn't simply the procedure or medication. It's the medical purpose for which it is being used.
Breast reduction, puberty blockers, and hormone therapy are not automatically prohibited for minors. They can be used in pediatric medicine to treat particular medical conditions.
For example, puberty suppressing drugs are used to treat early puberty, and hormone therapy can be used when a child has a hormone deficiency or fails to progress through normal puberty.
The disagreement is whether those same treatments are medically justified when their purpose is to alter or suppress otherwise normal sexual development because a minor is considered to have gender dysphoria.
So the comparison isn't simply, "cis teens can have these treatments but trans teens can't."
The distinction is WHY the treatment is being given.
Whether gender dysphoria in a minor justifies intervention is what is being debated.
There are more factors involved in making that determination than simply what the minor child wants.
Truth,
"American Medical Association (AMA): Affirms that transgender identities are normal variations of human expression and supports public and private insurance coverage for care.
American Academy of Pediatrics (AAP): Supports timely, comprehensive, and developmentally appropriate care for transgender youth.
Endocrine Society: Co-author of clinical practice guidelines for endocrine treatment of gender-dysphoric individuals.
American Psychiatric Association (APA) and American Psychological Association (APA): Support mental and medical health access while opposing discrimination and conversion efforts."
Which of these organizations specifically addresses the rights and responsibilities of parents to make medical decisions for their minor children?
Supporting a particular form of treatment is one issue.
The role and authority of the parent in deciding whether a minor should receive that treatment is another.
There has been a growing effort to reduce parental involvement in some decision making for minors, and many parents are pushing back against that. Parents should not be treated as an obstacle to their child's care. They are ordinarily the people responsible for making major medical decisions for their minor children.
Before you call the parents bigots, remember that their objection may have nothing to do with prejudice toward transgender people. They may simply believe that parents, not activists, schools, or organizations, should have the primary authority to make major medical decisions involving their minor children.
And that includes the possibility that, after considering the circumstances, they may decide that their child will not medically transition while they are still a minor.
