This book was fantastic -- it's intersectional, radical, and incredibly thought-provoking. Fogg Davis doesn't just point out flaws and discriminatory practices when it comes to gender definitions/markers (whether talking about government-issued IDs or college admissions or sports team qualifications), he makes a case that removing bureaucratic administration of gender is the only way to achieve gender equality. Then, he actually presents tangible solutions and ways to do so, complete with resources for businesses, schools, non-profits, etc. Can't recommend this book highly enough.
