It's not a matter of a better definition, but of acknowledging that the word has more than one meaning. When YOU say women you're talking about adult human females, and when "they" say it, they're referring to the status and social space usually occupied by an adult human female.
That definition confuses roles with physical human beings.
Look at the wildly different definitions of the word gay:
...
Do you think any one meaning is harmed by acknowledging different uses of the sound and letters in that order to signify a totally different mental concept? The purpose of language is simply to accurately transmit the thoughts of one person into the mind of another or others.
It's works both ways. Language can also be used to tell lies and to manipulate (propaganda).
Besides those who want (and believe it is their right) to include men in the biological sex category "woman", I haven't seen any definition of the word"woman" that changes its meaning from being a human being belonging to the sex that is able to give birth to babies.
As for the word "gay", saying "What a gay day!" now has a different meaning to the one it had before "gay" came to also mean male homosexual.
Redefining "woman" to also mean "man" renders the word "woman" as a signifier for "adult human female" meaningless and redundant. It erases women as a distinct group of humans.
How many participants in this thread do you think reject the fringe "misgendering is literal violence" claim, but would agree with me that calling transwomen men is controversial, insensitive, rude, ignorant, or something like that? Do you really believe I'm the only one? If so, would a poll be useful?
I don't know. 42?

I do know you're not the only one.
Yes, a poll could be useful and interesting.
BTW: What's ignorant about calling transwomen men?
What's the point of even posting in these threads if you aren't interested in changing anyone's mind?
To learn and discern what is true and what is false. It's a collective endeavour.
I'm interested in other people changing my mind. I regard this forum as a place to test ideas and beliefs amongst educated and intelligent critical thinkers who will, if possible, debunk beliefs that are not grounded in concrete reality.
If anyone's mind were changed by anything I posted, I would regard that as a million dollar miracle!
One can be an epistemological solipsist without being a dualist who believes in a mind body split, per say. Do you think beliefs aren't even real in people's minds? Like, would you say that concepts don't exist, even within minds?
The core of narcissistic perception is the delusion that feelings are facts: I feel like a woman inside, therefore I am a woman.
