While documenting his own personal identity struggles with gender and self-identity, British K-Pop singer Oli London explores the root cause of the issue of trans ideology and gender identity, tackling the pressures of social media, the education system, media, and other factors that are pushing a growing number of young people into transitioning. He takes a close look at real world examples and examines laws, research, and data to help lift the lid on the multibillion-dollar gender affirming care industry.

Gender Madness gives an intimate look into what led Oli London to want to become a "Korean woman" and how he overcame his battle to become an advocate for the millions of young people who question their own identity. He recently publicly announced he had detransitioned and is living as a male again and has since become an outspoken activist for children and women's rights, appearing regularly on numerous news networks including Fox News, Newsmax, OAN, EWTN, Piers Morgan Uncensored, Tucker Carlson Tonight, and Talk TV to campaign against gender affirming surgery in teenagers. This book shares his deeply personal life journey and his important message to others, all while encouraging readers to question the current societal trends and challenge their own way of thinking.
