“Transgenderism starts as a mental issue.”
No, you’re wrong.
It starts out as social engineering. Meaning a handful of communists concocting the idea, then figuring a way to spread it around through the schools and the media.
Transgenderism is an idea planted into the minds of susceptible people. It does not originate in their minds.
Maybe homosexuals are hoping ROGD (rapid onset gender dysphoria) catches on, so most girls get their breasts surgically removed.
