*TRIGGER WARNING - SELF HARM*
Thank you for asking questions instead of assuming that your experience, as a gender creative and gender variant child, qualifies you to understand and pass judgement on those whose experience was not the same as yours. Most of the cruelty and bias imposed on trans* people over the years has been fueled by those who were not trans*, but were gender creative and "outgrew" it or used "will-power" to "overcome" it.
There needs to be room in this world for people like yourself, to freely explore their gender creativity without judgement and without commitment, except to continue to be true to your self wherever it may lead.
There needs to be room in this world for people with gender fluidity, with mixed gender identities and expressions, with gender creativity that extends into adulthood and throughout their life. They should be loved and celebrated.
There also needs to be room in this world for people like myself, whose agony at the mismatch between my internal experience of who I am, and the way the world viewed me based on the outward appearance of my body, was nearly indescribable.
My first brush with suicide was at a very young age. There were many occasions with attempts at self-surgery to relieve myself of the worst of the dysphoria. I imagine this was not your experience.
I am glad that you got the help you need, and now have had peace and satisfaction with who you are, and hope you will allow those with different needs the same privilege.
I imagine you were not preyed upon by predators who sensed your vulnerability and difference, and could use your secrets to force you to keep theirs.
I imagine you were not taught from the earliest age by your all-encompassing religious community that a transsexual was the most evil thing you could possibly be, more evil than even a murderer of children, more evil than a false prophet who destroyed souls, as evil as the devil himself, and yet despite that, you persisted in retaining your knowledge of your true gender, even though it meant knowing that it made you irrevocably a monster condemned for all eternity.
I imagine you did not develop full amnesia in your attempt to distance yourself from the pain of your trauma, abuse, trans* identity, and internalized transphobia, and nearly killed yourself each time it surfaced for the next 30 years until you had healed enough to finally start living as your self, at which time all of your symptoms disappeared for good.
That's just one girl's experience, my own. But every trans* child I have ever heard about, even with the most supportive parents and doctors possible, have had to pass through hell to convince their parents and doctors to let them get the puberty blockers, and later when they are old enough, the right gender hormones etc. Many give up in despair before they make it that far; the suicide rate for untreated trans* youth is orders of magnitude higher than the general population; in an Israeli study, it was 80 times higher.
I recommend to you that you read the current WPATH standard of care, updated last year, which is followed by all physicians serving the trans* community. Your concerns about youth and the too early use of irreversible therapies is unwarranted. Even if you had wanted that at age 7, you could not have qualified for puberty blockers until you were well along in the Tanner stages of puberty, probably at 12 or 13 for most kids; and you could not have qualified for cross-gender hormone therapy until later, very rarely by 14 but usually closer to 16 or 17. Only a few people world wide have had surgery before 18, the youngest being about 15, and having lived in their gender for more than 10 years.
Please be aware that there are people who use language similar to that contained in your question, who call for the isolation and elimination of trans* people, and who use quotation marks in the same way that you did, as if to indicate that people's descriptions of their own experiences wasn't valid. I distrust any ideology, no matter how well intentioned, which denies others the validity of their own experience and pathologizes their own self-determination. I don't think you would do that, but human nature being what it is, it is very easy for intelligent young people such as yourself to get caught up in hate groups who masquerade as enlightened protectors of children.
