The OP of the thread blocked yours truly, Cervixen is absolutely correct
They can never answer what aspect of a person is erased or what aspect of human experience is "reduced" by insisting women are female and that sex is by definition reproductive role.
It doesn't exclude that ap person is a poet, or a friend, a charted accountant, a mother, funny, or caring, or insensitive or anything else. Literally all such an insistence excludes is being male.
It's all because, whether due to malfeasance or incompetence, they confuse necessary and sufficient, exclusive and non-exclusive propositions.
Literally every single one of their arguments is a variation on a logical fallacy (and is almost always denying the antecedent or affirming the consequent)
You're the only person telling women being female reduces us to our ability to get pregnant.
No one is reducing men to their ejaculate by referring to them factually as male. Why would describing the facts about a female person be reductive? Is it reductive to call a child, a child? If I say humans have two legs, am I reducing all humans to a pair of legs?
WTF do you mean my sex "reduces" me? Explain yourself.
A woman is an adult human female. That does not mean she must be fertile, pregnant, heterosexual, feminine, able-bodied, young, or capable of childbirth.
Infertile women are women. Menopausal women are women. Women with hysterectomies are women. Women who never want children are women. Only female people can lack female fertility. Only female people can go through menopause. Only female people can have a hysterectomy.
Stating that women are female does not mean “women are wombs.” That is you expressing your misogyny. That is not what saying "women are female" means.
The point is that women are human bekngs and human beings are male and female. Female people have been oppressed as a sex class because of material realities around reproduction, embodiment, labour, and male violence.
Pretending sex does not matter is not feminism and pretending the presumably "feminine" gender identity of a man entitles him to the rights of human beings who happen to be female, is a male supremacist movement masquerading as feminism.
You telling me what I am or what I am not is not any kind of argument. It's just narcissism and patronizing sexism.
