This is very non-silly logic. Why should I care about your chromosome configuration or sexual identification? It is not my business, and I expect you to respect that. Hence it is absolutely obvious to treat men and women equally and not adapt one’s greetings procedures to the gender of the other person.

After all, punching girls is exactly as appropriate as punching guys.

If you think that treating genders equally has nothing to do with accepting variations in social norms, then you're missing pretty much the whole purpose of the "treat women equally to men" thing.

Gender inequality is almost wholly a social problem, not a biological one. And

Yes. A problem where people find it appropriate for women to hug men but not for men to hug women. A problem where people find it appropriate for women to hug women but not for men to hug men. A problem where people find it appropriate to expect men to hug women. A problem where people find it appropriate for boys punching boys but not for boys punching girls.

You can hardly get any more gender-unequal than that.
