pmcollectorboy: Gender is an amalgamation of factors, biology only being one of them. Even with that one factor nature sometimes detours through. There's biological(XY chromosome). Chemical(testosterone). Anatomical(what you have between your legs). Neurotype(what you have upstairs). And to some extent sociological(society's dumb unspoken rules like pink vs blue, dolls vs action figures, and nurturing vs aggression).
Biological yes, chemical yes(though that's typically dependent on the biological, ie. men produce much more testosterone), anatomical(again typically dependent on biological unless something happened during development), neurotype yes(though again, typically dependent on biological, at least on averages across the genders). Once you know someone's biology, you can infer most of the other things you have listed, at least in terms of probabilities.
Your mention of sociological is flawed, however, at least with those examples given. There are clear differences between men and women that can be seen very, very early on in life. Girls are more interested in people, while boys are more interested in things. That's where the dolls vs action figures comes in, and men are more aggressive and competitive, while women are more agreeable and supportive. Those aren't traits that are imposed on them by society. Now of course any individual will have variations, but as an average of the whole, men will in general be less agreeable and more aggressive, while women will be more agreeable and less aggressive; among other differences. Men and women are different, but they are also equal. We complement each other quite nicely, we need both.
dtgreene: You really don't understand. Anyone who says she's a woman is a woman. Anyone who says he's a man is a man.
That's not how it works. You can't change reality just by saying something is true. I can understand the idea that a woman might want to be a man, or that a man might wants to be a woman, and I have empathy for their position. But I disagree with the idea that a woman saying they want to be a man, magically makes them into a man. They're still a woman, whom we can have empathy for and can refer to as a man. But that still doesn't make them male.
