Book excerpt: Trans rights and trans lives have come under increasingly vicious ideological attack in recent times, from the 'bathroom wars' and Donald Trump's anti-trans edicts in the United States, to attacks on proposed changes to the Gender Recognition Act in Britain. Laura Miles' new book brings together key strands in the resistance to these attacks - on the streets, in communities, in workplaces and in unions. It addresses the roots of transphobia and the history of gender transgressive behaviours, highlights trans people's fight for the freedom to live authentic lives and explains why that fight deserves unconditional solidarity in all sections of the left.
