How about reality?
A gay person can get as many dicks as they want shoved up their butt, but you cannot change your biological sex.
This thread is kinda veering off topic a bit, so I won't really go too deep into this but I don't think anyone is suggesting that transitioning 'changes someone's biological make-up.' That's what people who are against the idea of transitioning say that it is to make their platform seem like the only reasonable side of the debate.
The purpose of transitioning is to alleviate gender dysphoria, which it undeniably does and tons of research on this has provided evidence that in most cases yes, it does help a lot. Nobody is saying that their biological make-up post-transition is identical to that of a woman who was biologically born a woman. It's more about being able to look in the mirror and seeing a woman, and trying to have the world perceive them as a woman in order to combat their dysphoria. Depression rates are remarkably higher amongst those who do not pass or believe that they do not pass.
yeah them suicide rates aren't necessarily suggesting this
That's because treatment of transgendered people, while better than a few years ago, still has a road to go.
For starters the suicide rates of transgendered people take along anyone who's been treated in any way shape or form for gender identity disorders. That includes many people who did not transition, and you'll find that most of those that commit suicide ARE in fact those who either did not transition or whose transition did not help in their passability. A lot of the stunningly high depression and suicide rates also tends to come from them experiencing discrimination, treatment refusal, assault, and other nasty things.
Transition is for many the fix that they need. It's just not the right end-goal for anyone suffering from gender identity disorders. It's something that should definitely be treated on a case by case basis, but pretending that it never helps and that it shouldn't be allowed seems more like a personal objection to it than anything to do with your concern for others. If you said 'transition shouldn't be the first any only thing we grab for when it comes to treating gender identity disorders' I'd agree wholeheartedly. (though it bears mentioning that in most places, it's not as easy to achieve a medically assisted transition as people make it out to be. Many places require you to live as a your preferred gender for a few years before you're allowed to be put on hormone treatment), but I definitely don't agree that medical transition is something we shouldn't be making use of, when there's good medical evidence that suggests that it in many cases helps a lot.
