Book excerpt: Despite the name, trigger warnings have nothing to do with gun control, and safe spaces don't necessarily mean state-of-the-art panic rooms. Instead, these terms and the phrase "microaggressions" relate to preserving and protecting one's emotional safety. In this volume, readers will learn about the increased demand for sensitivity in social settings, in literature and media, and on the Internet. They will also encounter the opposing view, that we, as a society, are becoming too fragile and don't need figurative bulletproof vests for every occasion.
