People talk about sliding down the slippery slope until you hit the point of no return. Removal of bodily hair. Wearing certain clothes. Spending time in female-impersonation mode. Hearing someone call you "ma'am." You never know what might act as a "gateway drug."
None of that has to do with changing one's sex in order to fix a birth defect.
A sex change ought to be deliberate. The only sound reason to change anatomical sex is a persistent and overwhelming sense that the body doesn't match the brain. Clarity is essential. You have to know in your mind and in your heart that you have a birth defect and that all you are doing is fixing it. That kind of clarity is probably easier for a young person to achieve, before the corrupting influences of gaslighting and "normal life" have taken hold. The conspiracy works against clear thinking and, perhaps more important, clear feeling.
Even worse, the "gender industry" works against clarity as well. It's all about deconstruction, experimentation, and ambiguity. Of course everything in the world is not black and white. But when there is nothing but ambiguity, then all hope for clarity is lost.
You're either born transsexual or not. You can't slide into it. Sliding down the slippery slope into a sex change seems like a slide from a fascination with femininity through infatuation with femininity into addiction to femininity. Surely there must be better ways to deal with an addiction to femininity than to make irrevocable changes to one's body, one's life, and the lives of others.
