Be sure to let me know when you come up with a viable alternative.
Let's see...a "viable alternative" to drugging a child for eventual amputation of healthy organs to further their delusions with the aid of society's MDs...
..Oh, I don't know. How about deep regressive therapy to ferret out where the child got the idea they wanted to be the opposite gender in the first place?
For the perfect example: the boy in the OP. Quite obviously miserable in the shot captured in the OP photo, when he's not performing a cheesy-Pavlovian grin for the camera in other shots I've seen, the photo sports a virtual encyclopedia of clues as to what's going on with him.
Let's look again from the perspective of a psychiatrist who just had the boy referred to his office for said therapy:
The boy sits between two women whose posture is assertive, aggressive even. The one on the right even has the tight look of defiance, staring down the end of her nose at the camera. Just from the glance you immediately are struck that this boy has no choice. What these two women want from him is going to happen.
So he sits, old enough at 11 in this photo to know what's coming after the hormones they're drugging him with, with his hands clenched tightly over his groin. The look on his face is that of someone in deep grief and impotence. Like a prisoner about to be dragged to the gallows. On his pink trousers that you know he didn't buy for himself, are ground-in dirt stains. Seems the "little girl" behaves quit regularly like a little boy insteand.
At the rock bottom least, I would start off therapy with this boy by exploring one simple angle and then spiraling outward from there. And that angle would be "with two women acting as his adult role models; does this boy feel like masculinity or simply having a penis, gets you the emotional strokes and validation in a formative world where only women matter as objects of affection." I'd explore that maybe, just maybe this boy wants to be a girl so that he can finally feel like he is desired and welcomed and has a place in a functioning adult society.
And before we hear the predictable "well these trans children also pop up in hetero marriage"...I'll say that some women with 4 boys want the 5th pregnancy to be a girl so badly that word of that reaches the child's ears if the 5th was another boy. And in order to matter to mom (who is almost always the one insisting the boy wants to be a girl, and is the one buying the toddler pink frilly clothes, makeup and barbie dolls), the child easily "gets" that if they become that girl, them mom will really, really love them...(finally).
And vice versa with a dad who has too many daughters. He may select one of them who is more outspoken (a natural trait for a female) or assertive (also within the range) and groom that child to believe "she always was a boy"...
Other reaons present themselves. In Chastity Bono's case, she was always overwhelmed looking in footage I used to see on the boob tube when she was a tiny little girl. With a stunningly-beautiful mother who was always in the limelight, Chastity fell into the shadows. She was always just "Cher's daughter...what was her name again?...). So never feeling like she would rise to her own importance as a female or ever be as stunning as her mother, Chastity gave up being female. From the looks of her she adopted an eating disorder and then later decided since beauty was not achievable, better to be a "big strong man"...since "big" was something she already was.
All this stuff is due to the decay of Western society. It isn't any of their faults. So we must all fearlessly confront our part in telling big women "you're not beautiful" or men who cry or care about beauty "you can only be gay" or "you should have a sex change because you're really a female trapped in a male's body" Etc. etc. etc. etc!
So, the alternative to drugging kids for amputation of healthy organs later, is to come clean as a society, face the truth of our runaway exacting and media-fanned uber-standards for "perfection" in both genders (which is a form of social narcissism the US suffers from " We are always the best!..our males are the most male! Our females are the most female!!). Then we get these poor delusionals into therapy and teach them to accept their natural gender and its wide, wide range of possible expressions. ie: we grow up as a society and stop pushing everyone to be over-achievers.
