Question of fact? Earlier , someone posted that the correct term for m to f was " transwoman". Not at all an undisputed fact, among those personally concerned or among the psychiatrists and other professionals in the field.
This is because "transwoman/ transman" is a very broad term which refers to someone who falls somewhere on a very long line of differences; at one end to the other it goes something like ; occasionally crossdresses, /identifies with / dresses as/ lives as ( sic) / has legally transitioned/ has had hormones and/ or surgery.
In other words, the whole caboodle. Most of whom often have very little contact with or understanding of each other.
The reason that some of us, and our clinicians, use the term TS woman ( or TS man) is because we fall into the last category. We have made that commitment, to the binary position, and have had the help of medical assessment and surgery.
TS women and men usually don't like " transwoman" or " transman", and most of us don't use it.
