Look I respect their right of anyone to be called whatever they wish Trisher, my point is why do we all have to be redefined, I am not a "cis" woman, neither are the majority of women I imagine if they were asked. Heavens above! some women haven't even heard of the term, I posted before, a friend of mine was asked on a form at work whether she was one, her response "I've no idea, I don't know what a cis woman is" I think it's perfectly feasible for hospital staff to treat any transman who has given birth respectfully as individuals and, should they need to advice on feeding their baby ask whether they would prefer the word chest to be used. I'm sure as you say their number will rise in due course, I still think they will be an infinitesimal minority, which begs the question why change the terminology, when as Andrew Pierce stated on Jeremy Vine this morning, doing that is just going to piss off the vast majority of women off
