Well clumsy not by choice just lack of skill in this area.Dismal purple said:>Can I 'explain' to that person that while the other may appear to be male/female, 'really' they're female/male? Is this considered some grave offence against their chosen identity?
Your choice of words is the clumsiest choice of words possible and generally considered offensive, yes.
If the person who was trans was my closer friend then I would defer to their wishes and probably wouldn't even bring it up to the other person, but if the other person was a closer friend then I probably would 'clarify' the issue to them, assuming some basic competence in sensitivity on their part.
ETA - though after reading more replies I might rethink this. Plus it occurs to me that if I wasn't that close with the trans person, I probably wouldn't actually know they were trans in the first place, and if I knew they were trans that means we would be close enough that I would respect their wishes. If I knew someone was trans and we weren't close that means I only know because of rumours about them, which I wouldn't want to engage in myself (at least I would hope).
Fair enough, you don't have to feel stupid in telling me my question is stupid/irrelevant/too abstract, that at least helps me get a bead on things.>Is a man who knows they are a man and is comfortable with that, who then decides to become a woman, different to a man who feels they are in the wrong body? (would they still be considered 'trans' if they didn't have the 'gender dysphoria' part)
The diagnostic criteria specifically mentions that you can't be doing it for ulterior reasons. There is no mention of a person doing it for literally no reason, but if they had no reason they would not be doing it so your example is highly theoretical and silly and I feel a little stupid for answering to be honest.
The recent focus on trans issues might give the impression that being trans now is different to being trans in the 70's, so someone considered trans then might not be classified as trans now, that we are now at Trans 2.0 - is this true, or is it just the same as it ever was, but people have a bit more understanding about it now?
ETA - Thanks to all the others who've answered.
