my longest, exasperate sigh ever.... why can't these ever be about trans women? Not well oops ive magically become a woman and now that my bodies physically like this I guess it'd be wrong to not be a woman! Transition back?? Nonsense!!
god, it always winds up so cisnormative.
Eh, let 'em have it. It honestly seems like a fantasy in the same vein as "oh no, I was forced to wear a dress" or "woe is me, mistaken for a woman and have to play along". It doesn't just wind up cisnormitive it IS cisnormitive - always magic or something improbable because that's more relatable for the author than being trans. The point is to find something that forces the character into a different gender instead of them making a conscious decision, self-determining one's gender identity is a foreign concept to most people.
I didn't figure out I was trans from realistic portrayals of being trans but from silly stories and what-ifs, I don't enjoy them in the slightest now, but a few years ago they were helpful to me.
None of this is to imply anything about the author, just saying it's not such a bad thing, despite obviously lacking any understanding of gender beyond socially ubiquitous norms.
