Cisgender, het female. I would have zero problem with someone using they/them pronouns to refer to me. My assumption would be that that person was trying to be respectful and inclusive. I also think that being in a position where I would have to communicate my pronoun preference is good - it cedes just a tiny amount of my privilege and makes it a little bit easier for trans people.
Of course, I live in an incredibly liberal city where these things are taken extremely seriously. Not sure how applicable this would be to the general public.
