FIFY...

Um, this isn’t a situation where the person is merely different than they described. They’re a completely different person. If Newland is gender-fluid or trans, she still made up an identity other than the identity of Newland, pretended to date the victim as that identity, and then had sex with the victim as that fake…

No. Not the same thing. She was always a woman, even though her physicality did not match those of her cis counterparts, she was still a woman.

Ah, catfishing. Starts out as a lark, something fun to do while you’re bored, and then next thing you know you’re in England wearing a wool hat and a strap-on.
