Let's try this:
This is Karin Winslow (formerly a dominatrix) and Lana (previously known as Larry) Wachowski. They are married, and from all close sources willing to talk about them, soul mates who became changed people when they met before Larry became Lana. Gay?
I get that it can be confusing. Heck, when full sexual reassignment happens and they still prefer the opposite of their birth sex, it becomes very confusing. But ultimately, just let them live and don't impose stereotyped titles.
I was a manager at a company that had an employee which wished to identify as the opposite gender openly. In Kentucky. It became confusing for everyone. Bathroom rules were a topic of contention. Neither sex wanted that person in their bathroom. I am personally torn between how that should go. Part of me wants to say the plumbing should match the pipes, but that fails to respect the identification of the transgendered individual.
So, I understand that it's confusing. In this kind of scenario gay, not gay, bisexual, etc is hard to define. In fact, I've met transgendered individuals who can't decide and will argue about it.
This is one of the very few situations where I keep my non-politically correct comments to myself, because politically correct is hard to define.
