Jellyfrizz, whilst I appreciate your points about biological fundamentals that define trans women from women and that these are unarguable I wonder if you have considered where a cut off point might ever occur that crosses that divide?
In other words, is this a fundamental men cannot be women because of DNA, chromosomes, periods, pregnancy - and does that perception change if science chips away at these?
What is possible now is much different from what was possible when I transitioned 45 years ago. I volunteered to pioneer on a very small scale a form of FFS (facial feminisation surgery) that today is way more sophisticated after all those years.
Methods of surgery in other areas have improved to the point of creating a clitoris and self lubrication. Some trans women have always lactated and they now have method by which this is enough to allow trans women to breastfeed. Though it needs more testing to assure it is safe to the baby before anyone should go much further.
It is believed by specialists in the area that womb and possibly ovary transplants are on the near horizon for trans women. And that a trans woman may well give birth (by caesarean) before 2030.
Years ago trans men had little physical that could be done other than a mastectomy. Hormone treatment was very effective because testosterone overpowers female biology quickly and permanently. This is why trans men pass so well compared with trans women - especially those who transition late - because the impact of years of testosterone can never be eradicated even if it is reduced to normal female levels with surgery.
One of the reasons blockers are so popular with trans kids as they massively improve the female nature of a trans girl post puberty by stopping testosterone (from their perspective) wreaking havoc on their body. And with trans boys, of course, injecting testosterone has the reverse effect in a similar way.
I agree there are huge questions over when or how this should be done with children and it certainly has to be done with extreme care and certainty of necessity not in any way as an experiment.
But I know that had blockers existed in the 70s then 100% I would have taken them and it would have made a big difference to improving my life. Though I do see the negatives too that in the few cases where this will be the right thing there is a risk of doing it with the many more for whom it would be very much the wrong move.
So there are no easy answers.
Trans men now have also have increasingly sophisticated ways of creating a penis.
So step by step transition is physically moving towards more and more completeness.
When or if it will ever allow for DNA manipulation is another question,.
What I am getting at - though - is the trans women are men because argument based on today's reality? Or in a tomorrow where the degree of transformation moves towards 100% will that alter this perception? Or is there something more fundamental being objected to. Because trans women like me will unquestionably take every medical breakthrough going, however risky, to fulfil our quest for unity. And so at some point in the future this will be a question that you will have to ask yourselves.
