I mean all women. I don't feel I have the right to decide who's female and who's not. Except myself of course. [/quote]
Let me help you.
Female: reproductive sex class capable of producing ova.
Male: reproductive sex class capable of producing sperm.
Now many people have conditions that affect their ability to produce ova or sperm, but they're still male or female. You couldn't diagnose these conditions if you didn't know which sex class they are. Lack of sperm production, for example, isn't a medical condition in a female body.
And yes, there is a small number of people with a variation of development in either class. On occasion it can be confusing or misleading. But it's rare, and it's still a variation along one line or the other. Again, you couldn't identify it if you didn't know which sex class they were in.
Believe it or not, once upon a time, people didn't find male and female to be a baffling concept that required subjective "decision". When deciding who to send to war or who to deny a vote, they knew pretty well. Even now in these enlightened times, people who want to send death and rape threats, create crap gendered insults and erode rights can still work out who the females are. Oh, and gay couples who want to conceive can usually work out which gametes they need and which people can provide them. They are clever like that.
It's like we still retain some reptilian understanding of this difficult concept.
