Despite the differences in country, culture, decade, and follow-up length and method, all the studies have come to a remarkably similar conclusion: Only very few trans- kids still want to transition by the time they are adults. Instead, they generally turn out to be regular gay or lesbian folks. The exact number varies by study, but roughly 60–90% of trans- kids turn out no longer to be trans by adulthood.
He's right, fukking with these kids hormones and bodies is evil. 60-90% of kids who 'transition' end up reverting back to their real gender. But people refuse to listen to the science and instead let them permanently mutilate their bodies to solve a mental issue.
