For many - and I felt the same way myself for a long time - propaganda was something you learned about in history lessons. A topic that seemed to be firmly established: in the Third Reich, perhaps even in the GDR, i.e. in clearly defined, authoritarian systems. We were taught that propaganda existed there because these systems needed it - and that it didn't really play a role in an open, democratic society like the Federal Republic of Germany.
This view was comfortable. And it was plausible for a long time. Because propaganda was almost always shown as something obvious: as a slogan, as a poster, as martial imagery. Something that you recognize as soon as you see it - and from which you can distance yourself internally. Today, this certainty seems fragile. Not because people have suddenly changed, but because the form of influence has changed. And that is precisely why it is worth clarifying calmly and without agitation what propaganda actually is - and what it is not.
