It doesn't.
If you ask me, transgender people are more miserable and depressed as ever.
I still don't see how slapping on a pair of boobs or surgically attaching a penis and being injected with volumes of hormones would make anybody happy and comfortable. It's a case where the insane runs the Asylum and nobody actually wins in the end.
I can maybe see society overall adjusting to the frankly freakish sights that comes from such alterations and changes, and such, givin time could normalize some, but I think the illness will still be untreated with all the problems that compound the issues with people who decide to go this route.
