Radicalism usually has negative connotations in society and politics—anyone who is radical is not only non-conformist, but also extreme and therefore dangerous. The fear of taking a clear stance and making oneself vulnerable is, therefore, great. So at a time when the biggest social and ecological crises need to be tackled, there is a great deal of jumping around, shifting responsibility back and forth, and making vague statements. Those who call for urgent change and concrete action are labelled as hysterical and extreme. But a world with radical problems needs radical answers. In art and philosophy, radicalism is necessary, almost a prerequisite for productive debate. Radical attitudes also play an important role in design. Right now, a new radical wave of design is emerging that is striving for fundamental changes in the design order and questioning the design canon. Here, too, patriarchal hierarchies must be broken down and history rewritten—design must become decolonized, pluralized, and queerfeminist. The aim is to analyze this: What does radical design look like? How does it work? How can it act as a catalyst for change in society as a whole? Let's give radicalism a positive connotation and answer these questions. Let's finally get to the root of social and political problems and create fundamental change. Because radical is the new sexy.
