Again.
Female people exist.
Either the name "woman" is exclusively female, in which trans women are not women, or the name "woman" refers to some sort of mixed sex personality type, in which case trans women are women and we need a new word for female people because being female is still significant in some contexts.
What is not reasonable is this fudge where trans women are some sort of male woman based on their mind (which is sexist as fuck BTW) who we all have to pretend is no different to female people even though the basis on which thry claim to be a "woman" has nothing to do with our needs and challenges as female people.
The reasonable position between a big lie and the truth is not a smaller lie.
The reasonable position between having your whole house burgled and not having your house burgled at all is not just having the living room burgled.
This is not a "both sides as bad as each other" situation. This is one side wants to redefine womanhood as a type of mind, and in doing so remove any right to female-only support, language
This is why the reasonable way forward is not a fudge along the things of "some men are women some of the time, and other women just need to learn to share".
The reasonable way forward is to say "look, this thing you are labelling woman, objectively it isn't the same thing as what we've called a woman for, well, as long as humanity has had language really.
So let's get behind the language, understand what this bundle of thoughts and feelings and preferences that occurs in both sexes actually is, and then maybe we can build new social supports and structures and norms around it rather than trying to fit it into "woman" and doing terrible and unfair damage to the legal and social existence of the people who were already called "women".
