This is getting so silly.
It's not that hard!
Another reason why CISGENDER is such a useful word.
The Thai woman is a cisgender female.
She became romantically involved with an American transgender female.
They can be legally married here if the American's passport shows gender male.
They can't be legally married if it shows gender female.
Transgender Americans are allowed to change the gender on their passport.
I don't know what gender is shown on the passport because it's not mentioned in the press item.
