This is the part of the story that will drive the liberals nuts. One of the lesbians went straight.
I find that unbelievable. She may or may not be currently having sex with other females, but being married to a "sperm donor" doesn't make her straight.
"Britain married the sperm donor". Translation: "Britain married the father."
The legalities of procreation might be simplified if "donating sperm" always meant that the "donor" would have have equal legal rights and financial responsibilities with respect to offspring that resulted.
Who knows? It might lead to a rebound of "heterosexual marriage".
