Here's a couple of questions to throw some nice fuel on the fire.
1.) Does a post-op trans-gendered person have an ethical obligation to disclose this information to potential partners? If so, at what point?
2.) If science provides a method of genetically altering someone to truly be the other sex biologically, would there still be an ethical obligation? Would Galt then be forced to use the politically correct pronoun?
3.) If science has a method to genetically alter someone's gender and also a method to genetically change the gender dysphoria that causes one to feel of the opposite gender, which is the ethical medical solution to employ?
4.) If science only has a way to alter gender dysphoria and switching genders required the same rather "brute force" tactics currently, which is the medically ethical solution?
I like to consider myself open minded and generally don't care what people do in their own lives, but these questions do test that quite a bit for me. I do think there is an ethical obligation to disclose this information and pretty quick to potential partners. I also think that the current "solution" to gender dysphoria is pretty rough and dicey medical ground to walk. So lacking a method to truly change gender at a genetic level, I would assert that correcting dysphoria would be the ethical solution if it were available (and I'm talking about a non-existent scientific solution, not the pray-the-gay-away style solution).
