A very interesting discussion.
I think we are in fact seeing a gradual normalisation and, to some degree, a de-patholisation of the trans identity, but it varies greatly even among more open societies.
Certainly there are countries where it is now possible for people to change their legal name and gender marker with no need for involvement by anyone else. And the publicly run Center for the Treatment of Gender Identity Disorder here in Madrid has recently dropped the "Disorder" from their name, which is an important step, although I suspect this is more to normalise the public perception of transgender treatment and remove stigma. In the UK some of the criteria are being relaxed, maybe because the demand for services has increased massively in the last few years.
The thing, though, is that most of us still seek treatment in one form or another, and let's be clear that none of this treatment is in any way trivial, nor should it be treated as such: HRT results in body alterations and sterility, gender surgery even more so, and psychological services are by no means a benign intervention. Therefore, I do think that, while we may want to relax certain assessment criteria, we should take care not to trivialise what, for most of us, is probably the life event of biggest consequence in our whole lives.
I do a fair bit of semi-formal counselling in the MTF community, and my first recommendation is for the person to take very active steps to know their own mind, and to try separate out the various strands of their gender issues. And this is partly to avoid the person making a terrible mistake. For example, one of the people I counsel seems to most likely be a submissive crossdresser rather than a transwoman, so my advice to the person is to work with a psychologist, and only then seek a diagnosis. And with that diagnosis would come the pathology and subsequent treatment.
Not sure how much of this makes sense. I do not wish to suggest that my view is the only way to approach the issue, but I am a cautious person, and, over my 4 years on this excellent forum, I have seen too many people head down the wrong path (in some cases), and cause themselves significant damage and harm.
