I can definitely sympathize with stories about people struggling with identity and finding one's place in the world. I love coming of age stories. But here's where the distinction comes in. Coming of age stories typically end with the main character learning to love oneself as themself; or to put it another way, to love oneself as they were born.
Stories with trans allegories are necessarily alienating. The way most people struggle with identity stems from not being accepted for who they are. The way trans people struggle with identity stems from rejecting who they are at a molecular level. It's like the complete inverse of typical human psychology.
And I might as well put out this disclaimer. On its face, all of this doesn't mean stories written by trans people are necessarily always worthy of derision. Trans people are capable of being intelligent and putting themselves in the shoes of the general audience that isn't trans. But if a trans person makes a story that can essentially only be relatable to other trans people and it is intended for a general audience, then they're only opening themselves up to attack because to most people, their entire way of interfacing with the world is counter to biology itself.
