I can't actually believe that people are comparing this to a transexual/transgender. Transexuals/transgenders have a psychiatric issue of not being able to accept their clear (normal) biological gender and trying to change it by behavior modification, cross-dressing, hormone therapy, and surgery.
This clearly has NOTHING to do with a gene mutation that has caused an XY individual to develop, from conception and without any input of their own, into a phenotypic female.
Two hundred years ago, nobody would even know these women were actually XY. They'd just be amenstrual and barren.
As for me personally, if I was dating when I found out, I would break up because I want to have biological children. If I was married, I would accept it and adopt other children.
And the person that suggested that people who would tolerate a marriage to a phenotypic female XY are gay - he needs to get his meathead out of orthopedic surgery and think a minute about the stupid thing he's about to say before he says it.
