I compromise for cisgender people a lot in terms of gently educating instead of scolding when I hear them say something questionable about trans people, patiently playing along when they think my gender identity is interesting fodder for friendly debate and decide to play devil's advocate and challenge me on it, and answering questions honestly and openly, even if they're sometimes things that ought to be quite private (I do have my limits, mind~). Of course we shouldn't really have to be educators, nor should we have to argue for the legitimacy of wanting to be who we were born to be. But unfortunately the world we live in is one where a lot of people still don't know very much about trans people at all, and I do try to remember that, and exercise patience in a lot of situations where my immediate impulse is to bite off someone's head. (^ω^) With that in mind, I think I could probably date someone who was a little ignorant or naive about what trans people are, provided they came into the relationship with an open mind, listened to what I had to say, and tried to become more well informed rather than simply clinging to their incorrect, ignorant assumptions of what my gender identity signifies.
In terms of beginning to date someone who couldn't be seen in public with me, though... Hmm. I think I'd have to draw a line there. If you were to swap gender identity out for ethnicity here, and it became a case of, say, someone from a small, insular white community being happy to date someone of an ethnic minority but wanting to keep it all behind closed doors to begin with because of their own internalised issues about other ethnic groups, I think most people would agree that that is quite unfair and really rather degrading to the person of the ethnic minority. And I don't think that different standards should be applied with transgender people simply because ignorance about us is more widespread. I understand that such a reaction probably wouldn't be born out of spite, of course, and would be the product of uncertainty, feelings of vulnerability, and likely internalised homophobia and transphobia. But I would just find it too demeaning, upsetting and outright exhausting to be with someone like that. I personally think that if someone is willingly approaching the prospect of beginning a relationship with a transgender person but can't even bear to be seen in public together with their prospective partner, then the onus should be on them to sort out whatever issues are causing that, and it shouldn't be on the transgender person to compromise for and indulge those issues. Not fully understanding a lot of things about a new partner because they have a set of very different life experiences to anyone you've ever dated before is, I think, understandable. But I don't think it's fair to ask someone to begin a relationship with you if you're too ashamed to even be seen with them. I'd rather be with people who openly love and accept me as me, even if it meant being single and just hanging out with friends.
All of that being said, I would be a lot more lenient if the situation were closer to what Kitty described above, and I had transitioned from male to female midway through an active relationship. If someone knows from the start exactly what I am and is embarrassed to even be seen with me because of it, I'm unlikely to stick around, whether they want to be my friend or something more. But if I suddenly introduce a huge change into an important, already established relationship, then I think it's fair that I give the other party a little space and time to come to terms with that change. Doubly so if the change also forces them to reevaluate their own identity (such as having to accept that you are now someone who identifies as heterosexual in a gay relationship, or vice versa). Of course I wouldn't tolerate a reaction that amounted to outright hostility, but if someone I really loved and was invested in politely stated that they wanted a little time to get their head together and come to terms with a fairly significant change to the dynamic of our relationship, I think that would be fair. To me that's a very different thing to someone asking to date you, but wanting to keep it secret because you're transgender.
