> How are you going to take a grown man, whose physical traits are obviously different from a woman (broader shoulders, taller, more muscle mass, deep voice, not to mention his reproductive system, and other documented differences in other organs), and turn him into a woman? This is physically impossible and is akin to changing a banana into a fly.
Well, the spectrum of bone sizes / muscle mass do have crossovers between the sexes. Obviously you're not going to turn a 6'5'' 300lb man into a believable woman but if that same man starts to transition at 16? Who knows. And there are plenty of people who are well within the size parameters of the opposing sex even in adulthood.
> And physics and biology would still disagree with you. This warping of reality to fit some unscientific narrative is getting out of hand.
Disagree with what? I said for all practical purposes. Sure, you could in theory make a biological and physical distinction -- it just won't be relevant to 99% of people if the difference is not available to them. Does a multi-platform software user care if he's running the ARM or x86 binary? They are two vastly different beasts but if the compilers work the user has no distinction.
> They're two very different things. Flight is obviously possible because the inherent laws of physics allow it, and we observed other creatures do it.
You are missing the big picture. What we view as physically possible now will change, as it always has throughout history. Space travel used to be 'physically impossible', heck so did circumnavigating the world. We will eventually reverse engineer our brain structure -- downloading our consciousness might be feasible one day. Do you think people will care about XY chromosomes when they can swap bodies? Or in a world that heavily uses VR?
