Thousands of pages of books, millions of characters in tweets and hundreds of blogs have been devoted to explaining the distinction between sex and gender, but far from clarifying anything, bewilderment for ordinary people is only growing.The concept of gender is central to a vaguely progressive-looking set of ideas based on the maxim that people possess a so-called ' gender identity' . The real problem arises when this nebulous concept, bandied about with different and even incompatible meanings by different groups, is used as a prop to introduce policies that mark a huge setback for the rights of women and girls. The general public, watching the controversy from the sidelines, is confused by conflicting claims about whose rights are being infringed.In this incisive book, Laura Lecuona sets the record straight by reviewing the origin of the current uses of the key term gender and exploring the main theories of transgenderism. She discusses what lies behind the claims about pronoun usage and warns about the consequences of promoting the recognition of so-called transgender children. She points out the collateral damage arising from this activism, from the perpetuation of sexist roles to limitations on freedom of speech. She dares to confront the accusations of transphobia that often inhibit those who question the foundations of this financially-driven and increasingly dominant ideology and shows the devastating effects transactivism is having on women, both socially and politically. Gender Lies and Dangers is essential reading for the urgently needed conversation we need to have about whose interests are being served with the advancement of transgender ideology and what this means for women' s sex-based rights.
