It might be correct propaganda, for your definition of correct, but it is propaganda nonetheless.
Art usually gets repurposed as propaganda over a long enough time frame, but that's not what I'm talking about.
This is not a pejoritive: propaganda is useful, just like entertainment, and artists are often involved in all three. But not all art is created by artists.
Maybe I should not call it art - these artifact of an unspeakable, unsupressible urge to create. These are without purpose. They just are.
