In your opinion what causes christians to believe in Jesus

[Alan V]

What people usually mean by propaganda is largely nonsense. It is based on false and antiquated beliefs about the mind, like brainwashing or mind control.

Do bad actors attempt to persuade the masses of an ideology by disseminating information unethically? Obviously, but attempting to and succeeding at are two different things. And of course, nobody here actually thinks propaganda has worked on them, they just think it's worked on everybody they disagree with.

If you are trying to argue that only experts can talk about what is or isn't propaganda, you are posting at the wrong forum.

Propagandists play numbers games.  No method of persuasion is always successful, but they still get their numbers.

I have admitted several times, even redundantly and annoyingly, that I was misled by my early theistic training.  I prefer "conditioning" to "brainwashing" or "indoctrination," since the methods are most often positive rewards for "right" answers and negative discouragement for "wrong" answers.  That works great on kids, less great on teens.

However, propaganda also works by loaded terminology and thought-terminating cliches. Those control how people think, and they might correctly be called indoctrination.
