This is all wrong. Our definition of sex and gender are made up. It used to be if you had an innie or outie between your legs. We realized some had both. We moved to chromosomes and realized there were exceptions there too. Biology is complex. We learn more everyday. We constantly find our binary system is inadequate at describing humanity and sex as it exists. If you think visible diddly parts and chromosomes tell the whole story then you're probably wrong and your sweeping statements are ignorantly based on your inadequate understanding.
Rich. Gender is indeed variable by culture, typically as things that are considered masculine or feminine vary (i.e. east Texas masculine things are golfing and hunting but not so much soccer though other parts of the world that is different). Some cultures have other 'genders' but all are linked to biology and sex to some degree. Only the catcher is gay in Brazil, not the pitcher, because the pitcher is fulfilling the man's role. Other primate females react to crying human babies...because chemicals in the brain and neuro biology dictate it. Oxytocin isn't some made up idea, nor is serotonin, both of which are higher in biological females and associated with feminine behavior. I'd also ask how many people you know that have both sex organs and have gone through puberty as both. I'm not aware of any personally because all people are one sex or the other.
Please take your anti-science troll elsewhere. Or are you laying the ground work for molestation and abuse creating gays? I'm curious now.
