Book excerpt: Ten years in the making, well researched, pulling together peer reviewed science and personal experiences, On The Science of Changing Sex explains the deeper, less known, aspects of transsexuality and transgenderism. Sure to spark controversy, it delves deeply into the hidden world and secrets, often suppressed, the public doesn't hear about.This book is NOT the typical "born in the wrong body" transgender story. Reading it, you will discover that there is more than one kind of "transgender". You will learn the deep connection between transkids and gender atypical gays and lesbians and the shameful history of efforts to "cure" them. You will also learn about the way that cross-dressing men develop into autogynephilic transwomen. Kay also explores about the new fad of teens and young people falsely claiming "trans" and "non-binary" identities to join the "cool kids club" that gave rise to the myth of Rapid Onset Gender Dysphoria (ROGD). Kay Brown, herself a transsexual who was diagnosed as a teenager in the 1970s, while in high school, has spent a lifetime working to better the lives of transsexuals including co-founding the ACLU Transsexual Rights committee in 1980 among other notable achievements.
