Yes.
True some survived, but way more killed themselves than were alive. Also many were killed by others for being trans. The suicide rate has been historically very high among trans people. When you repeatedly tell someone they should exist, that they’re a freak for existing, they start to believe you.

If you constantly tell a group of people scientifically they should t exist, they will listen.

Suicide is a major problem in the trans community and those who stay say being allowed to transition is a major help.
Suicide is especially common among trans teenagers and children.

For most trans people transition is the absolute last alternative to killing themselves.
