The word "female" still has meaning.
A man is not female.
A cis woman is female.
A trans woman is female.
You are female.
I am female.
Biological structure does not determine gender.
You want the narrower definition, the exclusionary one that leaves some women out.
I prefer the wider definition, the one that allows ALL women to be counted.
Chromosomally, mammals are a lot more complex than your narrow definition. Bioneurologically, humans are a lot more complex than your narrow definition.
And the key thing is intent.
The thing that drives you is some kind of entitlement, some kind of fallopian-tube righteousness that propels you to police who gets to use the women's bathroom or whatever.
Most women have ovaries. Some don't.
I appreciate that you're very attached to this role of gender police you've created for yourself, but I have to tell you the sad truth - no one cares much about your prejudiced views. Except maybe the other TERFs you hang out with.
