it's kinda true in how popular media will reflect or reinforce popular sentiment unless its explicitly revolutionary, but if that's all the point is then it applies to everywhere and everything. Like the musical Hamilton is propaganda to excuse the American founders owning slaves

also Japan does often have issues with excusing or denying Japanese war crimes, like that completely evil hotel owner Toshio Motoya was putting pamphlets in the hotel rooms denying the Rape of Nanking
