The Youth Institute has published “Bookmarks”, a guide to combat hate speech on the Internet, which aims to be a brief and useful manual for the dissemination of concepts related to human rights and freedom of expression, as well as to raise and face the challenge of defending these rights on the Internet from a young perspective. It also aims to become a practical tool for action, training and awareness-raising work, aimed at both young people themselves and trainers, to establish in a simple way the essential concepts related to online hate speech and provide mechanisms to combat it.
