Having read through the replies I know I'm probably walking into a hornet's nest but all I ask is that my entire reply is read before you reply back.
As a transsexual, I know most would think I am going to try to argue against the OP about biology, but actually I'm not, quite the opposite in fact.
At the end of the day, there are only 2 sex's, male, female, and intersex is both male and female, so the biology still holds true.
There is a misconception both in law and in the transgendered community between transgendered women and Transsexual women, and I've often had this discussion in the trans community and I always get told to shut up by them.
I have a male friend I used to volunteer with at local Foodbank, he's heavily into A level politics and law, and we were having a discussion about trans rights and he said in law we are all classed as transgendered.
I was like nope, transsexual women are nothing like transgendered women, we nothing in common with them at all.
But, he was right when it came to law-making, the medical profession ties us all with the same term, so when laws get made about trans rights, I can totally get where CIS women are coming from, why you get so p*ssed off and angry over it all, I would too in your position.
Now I'm not asking anyone to agree with me on this, but this is how a CIS lesbian woman once explained it to me how she saw the whole trans rights mess.
She asked me what was the difference between being a transsexual woman and a transgendered woman?
I said, a transsexual woman mentally thinks they are female, but the sexual organs on their body are male, and they take the hormones and have the GR Surgery to transfer the male sexual organs to female sexual organs, hence the term Trans Sexual, Transferring from one sex to the other.
A transgendered woman uses clothes to create the illusion of being a woman on a temporary basis, they have no intentions of ever doing hormones and having the surgery, they are guys in dresses, some might be super feminine guys in dresses, but they still guys in dresses and transgendered covers everything from Crossdressers to transvestites to drag queens to those that do it for fetish / sexual reasons and god knows whatever else gets included in that spectrum these days.
The CIS lesbian woman said to me after I explained that: I can't have kids, I don't get periods, so if once your post-op you are not a woman then I guess I'm not one either, as I don't see what difference there would be between us, apart from you'd have risked your life to correct natures mistake.
The easy solution to the whole trans rights saga would be to simply say, once post-op you are that sex so you are one of us, and since those not doing that are just trans then they do not need rights as they nothing to do with you.
At the end of the day, I'm not here to try to convince anyone to think different, just putting my views with everyone else's, and to show we are not all the same.
Wish everyone all the best, and hope Y'All stay safe and well.
Blessed Be
