I agree with these changes.
GD clinics, funded by the NHS, should focus on those with a condition that is causing distress/problems not those who consider their gender status (for want of a better term) natural, normal and healthy. The change of name from GI clinics seems to fit with this.
I don't have problems with self referral. Presumably NHS England think this is the most efficient use of resources and the gender specialists are best placed to unpick whether someone has GD or another condition (which they can subsequently make a referral for).
There is no way the NHS should be funding intervention for people who are not suffering from a recognised or unrecognised condition.
