PS - or watching/listening to propaganda

If it didn't work it wouldn't be made. If you are aware of it, you can mute its effects.

I agree, but only to some extent; and one would have to be well motivated - for istance, doing research on the topic. And even then, one would need to take counter measures; such as mentally or writing down the actual truths to rebut the propaganda and methods.
