All good points. Sorry I’m coming from a non US perspective where climate change denialism is present, but less fervent. I like your definition of “truth from a rarified point of view”, though I might also considered non-rarified or pervasive, and factually well substantiated truths can be used as propaganda as well. The 95%+ consensus of scientists on climate change is both factually/meaningfully/importantly true and also used with a propagandistic flavour in many examples of political persuasion for example.
My post was more aiming at acknowledging propaganda as a vehicle of persuasion for any and differing representations of reality (political groups) that exists in parallel with the the establishment of facts of reality. Some representations will adhere more or less with the factual arguments.
