You ever read that red sails 'brainwashing isn't real' article? Similar premise, similar conclusion.
Basically guy was spending a lot of time debunking anti China stuff and getting frustrated. Realized really the propaganda isn't very sophisticated, wasn't hard to debunk in most cases. So saying people are fooled is kind of a cop out, underselling their intelligence maybe flattering your own. They're buying in consciously or otherwise because they see the benefit from siding with the propagandist.
Idk was an interesting read for me at least. If you can't get past the writing style these points are more or less where he ends up:
Stop accusing the masses of being “brainwashed.” Stop treating them as cattle, stop attempting to rouse them into action by scolding them with exposure to “unpleasant truths.”
Accept instead that they have been avoiding those truths for a reason. You were able to break through the propaganda barrier, and so could they if they really wanted to. Many of these people see you as the fool, and in many cases not without reason.
Understanding people as intelligent beings, craft a political strategy that convincingly makes the case for why they and their lot are very likely to benefit from joining your political project. Not in some utopian infinite timescale, but soon.
If you cannot make this case, then forget about convincing the person in question. Focus instead on finding other people to whom such a case can be made. This will lead you directly to class analysis.
