Matt walsh is on the right path. If there is legal drinking age, why not an age for getting such an operation, the person must be able to decide this themselves?
These operations are totally for cosmetics purposes, so a doctor/hospital cannot decide if they should carve someone’s private parts off or start giving them those drugs.
And if after that legal age a person decides they want to go ahead with it, they should not be allowed into men’s or women’s rooms, (as binary genders dont use each others restrooms, why should they). Other restroom arrangements could be made for them.
Finally, I apologise if I offended someone, this is just my personal opinion, I am open to any explanations.
