Not so. For one, trans women are women, but are not biologically female. For another, being a woman is primarily about fulfilling a certain role in society, having a certain relationship to people based on your gender and theirs. That's got very little to do with biological sex. Like I said, there's nothing biological about wearing dresses. Kilts and skirts are virtually identical, but one of them is seen as very masculine and one of them is seen as very feminine.
Nops. Trans "women" are not women. They don't meet any biological criteria for that, they can't operate functionally as woman. There are not trans-females in any other species, as this is exclusivelly a cultural and psychological phenomena in humans. As you said yourself, there's nothing biological about wearing dresses, thus, using a dress doesn't make you a woman.
As human beings, trans people deserve care and respect and the full set of human rights, yet, this doesn't include that we bend reality based on imaginary constructs.
Trans women are women. No other species may have trans individuals, but no other species has men or women either, or if they do, it's beyond our understanding (in the same way our understanding of their vocalizations or the way they think or experience is limited). Wearing a dress doesn't make you a woman, identifying as a woman and fulfilling that role in society does (which does often involve wearing dresses).
If you support trans people's right to exist as humans, maybe it behooves you to educate yourself about the difference between gender and sex, so that you don't repeat transphobic talking points.
Obviously we disagree on the fundamental point, but I appreciate that you took your time to have a civil discussion with me, and this makes me appreciate your point of view more rationally. I will definitelly think more about it. Who knows? maybe I'm wrong.
> If you support trans people's right to exist as humans
Absolutist statements like this ("if you don't agree with my point of view, that means your viewpoint is the worst of the worst") make people not want to look further into or agree with your ideology, and are ironically binary.
Those distingushing between trans women and women and those thinking trans people have no right to exist as humans are not the same group. You've bent this entire discussion to try and make it about the talking point you wanted to make, so hopefully you're pleased you did it.
