The sooner we get away from the postmodern fantasy of men and women being equal the better.
Any arbitrarily selected individual may be the equal of any other arbitrarily selected individual on any arbitrarily selected category.
We have different rules for behaviour for men and women
You nor Emily have done no work to justify this difference, nor the enforcement of such rules.
t's simply two different sets of expectations and standards
And the existence of these expectations and standards is called "essentialism" and "stereotyping" and both are ethically fraught.
We don't worry about women molesting men at parties.
I do. More, I worry that essentialist viewpoints will drive folks to "apologize" for some molesters and attack others. I blame the essentialism, personally.
Gay men some people behave differently than straight men other people.
Your statement is not actually true as you originally stated. Plenty of gay people behave identically to straight people. It's called "living in the closet", and it's done because... You failed to guess it: essentialism.
Those expectations of yours can go to hell
But they are more feminine, on average than straight men
You cannot use an arbitrarily selected group's central tendency to defend any view that prioritizes observing a group's central tendency over a member's individual qualities.
The average does not inform you of the individual.
I don't know how many times I have seen a piece of media whose message has been "even if you already know the answer you still have an obligation to ask your partner about big financial decisions first". Well, this is another one of those situations.
Even if you think you know the answer, the correct behavior is to assume you do not until that answer is explicit and rendered by the person being wondered about.
To that end you may "know" someone you know has a penis, you could have a mountain of evidence, but you will still be "in the wrong" if you say to any other human that they have one. You have a responsibility to still cast doubt on what you think you know unless they told you themselves.
Hell, they could have told you, and you could STILL be in the wrong by talking about it, unless they told you it was OK.
We all know it. Why pretend it's not so?
Because it is imaginary. You have created an imaginary average through the arbitrary selection of a group and now are expecting everyone to enforce the average against that group you arbitrarily selected.
In order to know "people" you have to know individual persons. Nothing will ever liberate you from the need to not treat people as if they are stereotypes.
People will tell you how they want to be treated, individually, and then it's your job to do that. Some of those descriptions will be stereotypical. Maybe even most of them! But you have the responsibility to treat people as who they are, rather than as who others who are not them are.
