These days mark 15 years since the outbreak of 15-M, that movement which now seems like prehistory to us, like almost everything that happened before the pandemic, and which many of my students don't even remember, either because they didn't live through it or because history books take too long to incorporate truly relevant events. And even when they are incorporated, we look for subterfuges to tiptoe around uncomfortable episodes, as has happened with the systematic burial of democratic memory. That 15-M was, relevantly, so for various reasons.
