I believe I asked you a question that you haven't answered, it is impolite to ask questions in reply to a question. Makes you seem like someone more interested in setting up semantic traps than engaging in honest dialogue. Which objective fact are you talking about?
Unlike the rants of Mr.Shapiro, biology does not show a simple binary of gender, because sexual determination is more complex than that.
Male and female exists in terms of sexual function. A male produces sperm that can inseminate an egg. Females have eggs that can be inseminated by sperm.
But that is a rather minimal definition, one which doesn't imply any particular form of behavior. Once you get to hormone production and expressions of secondary sexual characteristics, the picture is far more complex. On top of that, you have gender behavior and expectations that are mostly culturally determined, or culture at least plays a major role. So someone can be male or female in terms of purely sexual function, but not in any way resonate with cultural expectations of a male or female behavior or societal roles. So it is of course silly of Shapiro to dismiss sociology because it is not a natural science, as if he really has a clue about current discussions on gender in that field.
Same as above.
An answer so ambigious that it is meaningless. Male or female in what sense? Sexual function? Behavioral patterns? Filling certain roles in a society?
