@meccaBut transgender people have existed since the beginning of humanity... it's just a natural part of human diversity. Just one of the ways people can see themselves.
It's not a mutation. It has already been scientifically and medically studied and explained and people are currently learning even more about it and studying more it so they can know the best ways to help transgender people. Transgender people are people who have a girl's brain in a guy's body or a guy's brain in a girl's body, which causes them to feel gender dysphoria, which is stress about their mind and body not matching up. What helps their dysphoria and helps them to live a happy life is transitioning in some way to the gender that their brain sees themselves as.
The current best explanation for why gender dysphoria arises is that it happens when babies are in the womb. During gestation, their brain develops more towards one sex but their body continues to develop towards the opposite sex. Hormones are what shapes the baby's mind and gender identity, so a transgender person who is biologically female would have probably had less estrogen come into contact with their brain in the womb which leads to them feeling more male/masculine and giving them gender dysphoria when they grow up... and the opposite happens for biological males who end up transgender. Studies have shown that transgender people's brains more closely resemble the brains of the gender they see themselves as rather than matching their biological sex.
The longer, louder, and more often you post this does not make it true.
