Difficult question, it would depend on how far she went into the trannydom (pills, surgery, etc), and how far she is from it (not "identifying" as such anymore, completly rejecting the marxist notion, etc).
My wife is a tomboy. She always was, never wore makeup, never wore dresses, played football with the boys in the courtyard as a kid, all that stuff. If she grew up in current year instead of decades ago, it is quite possible that some fucking teacher would have referred her to some fucking psychologist that would have diagnosed her as a tranny because she's not girly enough. As a suffering teen (like most teens) she could have agreed with the notion and went along with it. She was merely lucky to be born in a less corrupted decade.
I don't think I could date a woman with zipper tits, or that took pills that changer her voice/facial hair forever, but I could forgive a girl that went along with what "the adults" told her when she was a kid/teen and then grew up to see what bullshit that was.
