The rise of hateful expressions in recent years has surprised Europe, where important social consensus that were to be stable. Fundamental rights around discrimination are being violated, resulting in affected social groups being actively impeded from developing their lives with dignity This guide arises from the need to correctly understand the concept of “hate speech”, a concept which was worked on at the II international seminar, organized by Eskura (Center on Human Rights Pedagogical Resources) in February 2020. In the first two chapters, the author, Paloma Viejo, introduces us to the difference between “hate speech” and what we have called “speaking hatefully.” These two terms have become confused, using “hate speech” now to refer to both issues. These chapters will thus seek to clarify this misunderstanding. The third chapter open with the dilemma regarding the limits of “freedom of expression” and “hate speech”, tracing its origin right up to the current formulation of “freedom of expression”, as laid out in the Declaration of Human Rights. The chapter then ends with a discussion of oppression and the situation of oppression that arises if not properly regulated, which, in many situations, is not easy, as we can see from the situation today. Chapter Four outlines the guide main ideas. The guide then concludes with some pedagogical proposals for each chapter, which seek to complete and assimilate the theoretical sections. Although aimed primarily at professionals from public bodies and associations, they are also useful for anyone interested in understanding these issues. We hope this guide helps us better understand all of the above terms and their importance and contributes to create a more just and fair society. In addition, the guide intends to be a contribution and a complement to the rest of the documents and guides that address these issues.
