Interventions at every educational level, in both formal and informal contexts, are necessary to combat damaging, discriminatory, and violent discourses that manifest online and offline as xenophobia, racism, antisemitism, anti-Muslim hate, and other forms of intolerance. In addition to the more general objective of creating inclusive societies, this book provides specific suggestions, best practices, and lessons gained on how to stop hate speech and provide secure and courteous learning settings.
