Agree, some over-thinking may be in evidence. Also quite a few 'facts' based on rigid gender assumptions.
As another 5'8", sturdy peasant type, I've often been thought a transsexual (I'm a hetero woman). This happens mostly in countries where people are smaller & lighter of build, women tend to have more pronounced femininity - and there is an accepted social stratum of intersex 'women'. It's no more than a genuine social error in those circumstances. (I was once followed all the way through a mall by a gaggle of teenage girls, hotly debating whether I'm a man or woman! Didn't let them know I understood, just chuckled to meself.)
Over here, if anyone tries to insult me by calling me 'like a man' or 'a tranny', I ask them what they mean. What they mean is always something I'm content with; they're just displaying their own preconceptions & sexism. Oh, exception: I can't wear frilly frocks: to be fair, I do look like a badly-dressed transvestite in them!! Especially if my hair's gone flicky-up at the ends.
I've had loads of arguments interesting discussions with retrograde, hetero males who've done the "OMG, I went to pub and realised it was a GAY bar!!" horror display. What they find scary is that they think (conceitedly) that they'll become prey for all those scary gay men. What this shows is that they think of themselves as predators in a mixed, hetero situation. They've also never registered that the majority of the women they 'prey' upon have politely rebuffed them, just as they could if a gay man were to hit on them.
What about cultural differences? Arab cultures may be horrendously sexist, but their insults are mostly penis-related: "Describing someone as a 'fatah' (foreskin) is considered a grave insult"
This is an entertaining, informative page!
