Otherwise you could claim a crossdresser were trans or people who claimed they were “attack helicopters” would have to be accepted as trans because there would literally be no argument you could make against it.

this just sounds like a skill issue on your part, i’m sorry–this is not an issue if you have a postmodernist understanding of gender, which most trans people (myself included) subscribe to.

at the end of the day when you drill down? there really is not a material difference between the “real” and “fake” genders–gender is entirely socially constructed, and the designations of “male” and “female” that most people fall into are as arbitrary as any xenogender (real or frivolously created by right-wingers). you only “lose” by entertaining frivolous designations if your understanding of gender is already so narrow that you can’t conceptually accommodate anything beyond a handful of stock gender identities to begin with.
