It has to be something such that babies, animals and people in tribal cultures can be classified as female or not.
Why? We use the word "female" when referring to babies and animals, but that doesn't mean we're necessarily talking about the same thing as when we refer to adult humans; and if we are, it doesn't mean that we're talking about something they actually have. (I assume that it doesn't make sense to talk about whether a baby is straight or gay, for example.)

Why not?
I assume that it doesn't make sense to talk about whether a baby is straight or gay, for example.
Well, according to the (admittedly rather dubious) party line being gay is an intrinsic property and not a choice and most definitely not subject to environmental influence by pro-gay memes.
Heck, the official (and even more dubious) party line on trans-people is that they have always been their gender trapped in the wrong bodies.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
