If merely having XX chromosomes is enough - then yes absolutely. There are XX trans women who exist. Then no, I don't agree with you. I don't mean that transmen/women don't exist, I know a few, 2 for many decades. But I don't believe, and nor do they, that they were born in the wrong body, they both believe they have gender dysphoria that extensive surgeyr has somewhat alleviated.
I am also fully congnisant of the term 'legal fiction' and the reaosns behind the very many such laws we happily live with. It is when they are held up as incontrovertible truths that there starts to be a problem. So legally a transwoman is a woman, genetically a transwoman is male, and transmen are legally men yet remain genetically female. The amount of surgery never used to really matter - until the rather determined attempts at making that legal fiction biological reality began. Then, I am afraid, those who made that stand rather threw every trans individual under the bus, and made many women less accepting and more angry, defensive and much more likely to refuse to continue with the status quo.
Why, you ask? Well, because I am female, a woman, I have spent my whole life living with the every day realities of being perpetually vulnerable to some penises and some penis wielders. I really don't want to be forced to share enclosed spaces, safe spaces, with an unknown penis haver because my fears are based on past experiences.
If you don't understand that then a) you aren't a woman and b) you need to ponder why your apprently disingenupus question is getting some raised eyebrow replies. Hint only a man could ask that question as he would not have experienced the every day fear of the unknown man that walks a little too close, looks a little to long, shakes hands a little too enthusiastically, asks questions a little too personally or flat out disregards a polite backing off, or no... nad calls you a slag or whore, or accuses yoi of being delusional if you think he was trying to grop you, you beig a fat slag and all!
And I'm not being hysterial (gotta love that word), using hyperboleor overstating the case. Women live with a perpetual second guess all the time. It is so usual we barely notice we do it, but OMG does society go to town on the woman who forgets to live in fear, to be adequately paranoid and walks home alone... and meets that man
Have a think.... and then just maybe you'll be honest and agree that we women might have a point and your question really was disingeuous, at best!
