Yeah I even assumed "Suzy" was a character or something at first, kinda like Borat, used to make a some statement; that just feels like an Eddie Izzard move. But based on the new information, it seems like "Suzy Izzard" is correct and sincere?

It is a bit of a shame, since it does somewhat undermine the strength of dressing how one likes despite gender norms; bolsters the narrative that that's just part of the pipeline, and not valid in and of itself. But, she's not compelled to moderate her expression in order to uphold some banner of transvestite representation. She can obviously do whatever makes her happy and I'm happy for her
