What do single moms, stay-at-home dads, professionals who happen to be women, men who like to dress colorfully, infertile people, and homosexuals have in common? They're often viewed by society as sad, bad, and even a little suspicious. Those judgments all stem originally from one idea: that females are naturally passive and more caring, and males are naturally aggressive and more intelligent. It's an idea that is deeply embedded in our social system and dictates much of our behavior. It's also an idea that has nothing to do with what's actually going on in nature. Crime Against Nature exposes the true diversity of natural behaviors. This 13th anniversary edition uses OpenDyslexic, a font that makes reading more accessible, and it comes with two new images as well as a preface that addresses 2025's challenges.
