In the summer 2018 we gave a course on Gender theories and Sexual and Gender-based Violence prevention for 10th graders of German School Madrid, Spain. In the course we deal with the following issues: What kind of stories do we tell in our media, sciences and in daily life, which fix certain gender roles? Sexual and Gender-based Violence (SGBV) is direct, structural or cultural, hence it is partially invisible. We talked about history and current facts on SBVG as much as about its resistances. In this context, feminism, ‘the radical notion that women are humans’ can be seen as a movement that concerns everyone as it searches for social equality at all levels.
