What a horrible analogy.
You presented a ridiculous notion that because some things doctors do are scientifically sound ... everything they do must be scientifically sound. I should have just said ... don't be retarted.
Oh you didn’t even understand what I wrote. That’s a problem. If you want me to clarify anything, just ask.
How I could be convinced of what?
Do I believe in gender dysmorphia?
It’s body dysmorphia and gender dysphoria. La Xasop should add this to your list.
Sure. Sounds pretty legit. Tick. It's a thing. Likely requires lots of therapy assuming it can every be cured/improved.
Do I think scientists/doctors can change your sex because they say they can? No. They cannot change your sex. They can call you 'she' as much as they like but every cell in your body has a y-chromosome. You are utterly male, albeit now mutilated in some way by them either with hormone treatments, castration, silicon implants ... whatever. None of these things change your sex and when doctors call it a sex-change ... they are lying. They cannot change your sex. There is no trans. You aren't transitioning.
So your problem is just that trans women can’t produce ova and trans men can’t produce sperm? If that’s it, then we are talking across each other. Yes, at this time, we can not change primary sexual characteristics of people surgically. How would your position change if we could? It seems a complicated but eminently solvable problem.
As a side note, you can be born male with no Y chromosome. Biological sex isn’t entirely binary. The definition of biological sexes is based on the gametes the organism produces however you have humans that produce both or no gametes. Biological sex and the subsequent gender roles attached to them are not cut and dry issues for some small subsect of people and the more it is studied the more we have moved away from defining transexuals as delusional. It’s a similar process that society went through with homosexuality 40 years ago and the change to acceptance is playing out in a very similar way, on a social level.
