We are "entrenched" because we've thought about this a lot more than you have.
We have covered all the angles. We have considered every argument you have made many times before. Some of us have made them ourselves on the way and had the same holes picked in them.
All of us have genuinely looked for what we are missing that makes trans women genuinely, objectively more like women than other men such that all the reasons we sometimes separate men from women no longer apply to them.
Honestly, every woman on this thread would love there to be some point we missed that makes all the objections melt away so we could all go about our business in other things, comfortably back in the Leftish Progressive fold.
But it just isn't there.
So no, you don't get to a discussion as "tedious" simply because you are realising there are counterarguments to every naive "solution" you come up with to make some men somehow more like women than other men.
Thst feeling, that frustration that you just can't find the words to get through to us what you know, you just know, is right? That is the start of realising that maybe, actually, you aren't right. That maybe the obvious conclusion, the one you are too sophisticated and openminded to fall for, that trans women simply are just men, maybe that is actually the truth after all.
Hopefully however you will go away and start thinking more deeply about this. Most of us start where you are, assuming there must be some better answers because surely no one, no one, would be making these on the face of it outlandish demands that some men are really women and need to be treated as women if there wasn't a genuine real basis for trans women being more like women than other men.
But there isn't. There really isn't. It's all just sexism (for the "genuine" ones who do believe it of themselves) and power and fetish for the others.
Because female people exist. And just changing what the word "woman" means doesn't move a man any closer to the reality being female. And once you stop looking at the trans women and what they need and why they need, and look instead at the women and what they need and why they need it, the difference between the two and the unfairness if making women-only provisions, rights and even language over to male bodied people based on a "feeling" of womanhood are obvious.
