Welcome to gal-dem's Roaring Twenties. This issue asks what could the 2020s look like, and what do we want from them? What can we learn from organisations like The Advocacy Academy, which is training new generations of social-justice campaigners? What does a world look like when we re-evaluate our attitudes towards drugs, towards housing, towards whole industries? As we progress through (and for one of us, past) our twenties, what parts of our histories do we cherish and hold close? Who are the artists, makers and creators we want to champion today and tomorrow? We have created this edition full of hope for a new era, one that harnesses the nostalgia of the recent past as a tool to drive us forwards. Invigorated by a new century, and acutely aware of the past mistakes we cannot replicate, this edition asks us to imagine how we can make the 2020s roar in their very own way.
