@ryanhoulihan society at large, aka most people, value conformity over health or happiness.
They don't want to see anyone thrive, they want to see everyone in exactly the same mental state they are in because if a person is different than them its disturbing their egocentric reality.
Its kinda ironic, Japan as a whole gives far less of a fuck about trans as long as you entirely assimilate into the bianry role you choose than they do about open homosexuality.
It boils down to presenting as "normal" regardless of anything.
The anti trans people will never be ok with trans or LGBTQ or hell, often cishet people of the opposite sex in many cases, and god forbid you have a different skin color.
