No, what I am saying is that Bob's sex is male. His gender may vary, however, depending on who is assigning it, and by what criteria.
I think the problem here is that psychologizers and liberals are getting carried away by terminology. "Gender" is not some kind of magical word used to describe something occult and mysterious.
It's a word used to describe something perfectly pedestrian and mundane. Again, the possible options for "gender," when referring to people, are "man," "boy," "girl" and "woman."
When talking about nouns, the possibilities are "masculine (male)," "feminine (female)" and "neuter."
What you mean by the "gender of Bob" is simply: "Bob's being a man" or "Bob's being a woman."
So what you are actually saying, PureX, is this: "Bob's being a man depends upon somebody's perception of him, whether his own or somebody else's."
In other words: "Bob is a man if and only if Bob is perceived as a man or has 'to be a man' assigned to him."
Which is, of course, doubtful at best.
"Bob" is Bob. His sex is defined by his genitalia
I actually disagree with this. It's the other way around: genitalia are signs of, express and are defined by the sex which correspond to them. Male genitals do not make men. Rather, men naturally have and develop male genitals.
A male set of genitals is simply one of (or a set of) the organs which provide for the completion and perfection of a male animal.
If a male should lose his genitals, he, for all of that, does not cease to be a male.
, and his gender is assigned to him subjectively, by whomever is doing the assigning.
Why should I think this?
Bob is more than his sex. And Bob's gender involves much more than his genitalia.
He's more than a lot of things.
Bob is:
A substance
A bodily substance
A living bodily substance
A sensate living bodily substance (an animal)
A rational sensate living bodily substance (a human being)
A male rational sensate living bodily substance (a man)
This male rational sensate living bodily substance (Bob)
This male rational sensate living bodily substance with the accrual of all of his various accidents (being such and such a weight, being such and such a height, having such and such education, life experiences, etc.). (Bob, a middle class short fat man who works as a music teacher, is married and has three children.)
So I guess if you want to be a simpleton, and ignore who Bob is in favor of his genitalia, then for you, Bob is and can only ever be a human with a penis. But if you are not an ignoramus, or a simpleton, then you might want to consider Bob as a whole person, having not just genitalia, but a personality, and an idea of self, including a great many unique and individual proclivities that make him who he is among the rest of us.
You have yet to provide an actual argument for the proposition:
"Bob is a man if and only if he is perceived as or given the assignment of being a man."
You've simply dogmatically asserted it and insulted me when I disagreed.
