"Propaganda" is intentional deception. (even if the deception is only to very selectively present real facts (partial information that is misleading by itself) with suggestions of interpretations, to create a false impression)
Propaganda is lying in some manner. It is not for instance a policy or idea you or I disagree with but that the person saying the idea/viewpoint believes is correct.
If some individual (it's a big nation) is somewhere saying what they know is false, intending to mislead, then that could be actual propaganda, of course.
Is there a lot of that? From my experience, admittedly way back in the 80s, definitely not. The few professors (very few actually) that had wrong viewpoints were quite sincere and themselves really thought they were correct views. ;-) (After I challenged one viewpoint, I happened to see the prof later in the library actually looking at books, and since he withdrew from the course, I couldn't help but think he had been sincere, but perhaps began to be less confident in those views.)

For example, it's propaganda for talk show hosts to suggest that generally protesters are violent or lawbreakers and full of people that do looting, vandalism, etc., by selectively emphasizing the actual real looting and vandalism, and suggesting, falsely, that most all protesters are of that same motive/action/character of trying to 'end America' or such.
To paint the real wrong of the few onto the innocent many.
Such lying prevents any person doing it from having a chance to enter heaven, unless they repent.
