Now we're getting somewhere. At last.
"Well this is one of the problems with current medical practices. I'm not sure I quite have the stomach to go into this here though, as I think it will be too much for people, and is only going to invite a load of anger directed at my person if I do."
If you have something to say, then please say it. If you don't want to say it then why waste time alluding to it?
"gender dysphoria is the distress that results from being trans, so while a person may be trans without being gender dysphoric, the diagnosis doesn't contemplate a clinical diagnosis of gender dysphoria in a person who isn't trans."
So if someone is diagnosed as gender dysphoric they must be trans, and the cure for gender dysphoria is transition?
"I do think people can have symptoms/ experiences of gender dysphoria without being trans, but these wouldn't meet the threshold for clinical diagnosis."
So you are saying that some people can be mildly gender dysphoric without being clinically gender dysphoric, and that these people would not be diagnosed? Can you not see the risk that some doctors might make a mistake and tell someone that they are clinically gender dysphoric and the treatment is transition, when in fact they are not and instead are only mildly gender dysphoric? You do realize doctors are not perfect don't you? They make mistakes.
So. Jackie says she's trans. This is not a medical condition nor diagnosable. She goes for a gender dysphoria diagnosis to see if she is gender dysphoric. If they tell her she is then the cure is transition. If she is not dysphoric, and does not have the medical condition of "being trans" (because being trans is not a medical condition), she may still choose to transition, which is a cure for dysphoria which she does not have?
Or do you think transition is inappropriate for trans people who are not dysphoric? What does it mean to be a non-dysphoric trans person?
