This is what is so funny about you gender cultists; you claim that gender and sex are different when you're trapped. If gender and sex are disconnected, then a transwoman is not a real woman. Transmen aren't real men. You know this, so does the rest of the rational world.
Further, if the silly linguistic gymnastics used to obfuscate clear reality hold any meaning, in your deluded world, a person identifying as a gender that is opposite of their biology IS, in fact, that opposite biology. Therefore, if they later choose to identify as the only other biological reality, they can't have reverted rather, they changed anew. It's asinine.
