“But this concept of physical sex as permanent and inescapable is actually incomplete, inaccurate, and irrelevant.”

Oh. My bad, dude...

I would have to ask the dude (it)?
If this is so normal, why have I never read any historical accounts of any man whipping out his hatchet or pocket knife and chopping off his pecker?
Nothing from 200 years ago, nothing from 100 years ago, nothing from even 50 years ago?
Did this identity/gender changing thing just become normal when medical science was finally able to develop anesthetics and surgical procedures good enough to whack off your pee pee without you bleeding to death?
Obviously if this has been normal and a physical imperative, there should be some record of it in the medical literature of the past, right?
