I don't think any of us know how representative the affirmative position is with the EP or CP professions. We only hear from the representative bodies (who we know aren't operating from a position of representing the majority view) or those who battle it out on Twitter.
What I would say, with some confidence, that the current climate has resulted in poorer quality psychological support. Psychologists are taught to ask lots of questions and generate broad hypotheses. I supervise lots of psychologists and many significant restrict their questions and hypotheses.
None of the following undermine a young person's gender identity, but many psychologist fear that they could be perceived to (in giving the example of a female young person who describes themselves to be a trans boy)
Tell me about the thoughts and feelings that go on inside of you that make you feel like a boy? How do you think these would be different if you felt like a girl?
Other than internal (inside) thoughts and feelings, what differentiates boys and girls?
Is it better to be a girl or boy? Why is this?
What are the best things about being a girl (do you think)?
What are the best things about being a boy (do you think)?
The skilled psychologist would develop a relationship with the young person that helps them to mentalize (think about thinking). They would create an environment when the discussion reflects exploration and reflection not challenge and 'gotchas'.
My work with young people with gender distress achieves this. Many of them really struggle to mentalize due to autism and personality disorder. Others struggling to mentslize simply due to the levels of distress they experience.
I feel my work is very defensible, even under current 'requirements' from trusts and regulatory bodies, which is why I persist.
As I said, some colleagues struggle to have the courage of their convictions to work in this way, which is how they work with young people with every other presenting problem.
Following supervision with me they are presented with the ethical dilemma of working inline with what they understand their union and the BPS is advocating, or in line with what they were trained to do and their clinical reasoning suggests they should do.
