Bruce Jenner talked about dressing up as a woman when he was like 8 years old, and how confused he was by his own actions. He didn't advertise that when he was closeted, which makes a ton of sense, right? You don't remember it because you don't know if it ever happened to somebody close to you.
My cousin and his wife are devout Mormons in the heart of Utah. Their daughter was a really cute little girl by traditional standards. She grew up going to church. If there was indoctrination, it was anti-trans indoctrination. She even graduated from BYU. So when did adults confuse her? She has Endometriosis and PCOS, which causes elevated testosterone levels and she's not such a cute, little girl anymore. I honestly can't believe she's the same person. She looks biologically different from all her peers of her same birth gender, and naturally, she has gender confusion.
