A guide book that will help teenagers and the adults around them recognize violence, stop being silent and start acting. Violence in the modern world can take different forms. The path from seemingly harmless remarks and made-up nicknames to bullying, sexual harassment and physical attacks turns out to be not so far even in the 21st century. The author of this book, science popularizer and journalist Emma Strack, explains in detail how toxic mechanisms are triggered in any team, what parties involved in what is happening, and how caring, respect, solidarity and empathy can break the vicious circle of violence, aggression and discrimination. You will learn why victims of violence are not to blame for what happens to them, why it is so difficult to decide to talk about the aggressor, or even just to say no, and what steps we can all take to improve the situation. There is a way out. The book can be called a desktop reference book on the fight against violence: in addition to world and Russian statistics, here you will find links to laws, various websites and hotline numbers where you can go to talk about your problem and get support.
