In my TG support group I am one of a pair of odd ducks. Everyone else has either transitioned or in the middle of it. Every newbie during the six years I've been there came in scared and clueless. Within several months full-time. It has only been the oldie tymers that are reluctant. Which usually isn't long between marriages collapsing after dropping the T-Bomb followed by the WTF, I lost everything that matters. Even my life means nothing anymore.
I totally understand your response to this group. Today's youth have barely no social impediments to transition or non-binary living. Plus being young you have no skin in the game of life. Making such a life change entails far less risk. Especially when you see no hope of a future and no past to hang on to.
I also suspect there was the overwhelming consensus that there is no other "Cure" besides transition so why fool around with anything else? As I try to get a younger member to grasp, there are plenty of reasons one can have to try or experiment with other methods to "Manage" the GD. Reasons such as a spouse, family, career, and other important aspects of your life you do not want to put at risk. Like trans v cis, if you don't have things like a wife, kids, a great career, somewhat functional family etc., you don't and really cannot "get it". There is no frame of reference for you.
