I will say this that if you think you are immune to propaganda, then you have been propagandized. We are all susceptible.
There is a reason why the phrase "you can fool all of the people some of the time" is included in the phrase "you can include all of the people some of the time and some of the people all of the time but not all of the people all of the time".
A very apt example that still riles some people's feathers is that some people still hate Hillary Clinton.
Not just like a dislike or an aversion, but an actual personal hatred.
This hatred is from propaganda, and pretty much any time it is mentioned somebody will crawl out of the woodworks to explain exactly why they hate Hillary Clinton.
