I forgot to say what I think of the video (how did you all sleep not knowing?)
It's OK I suppose. Bit long for me, and it's just one man's way of organising some ideas about propaganda. I don't usually find other people's way of organising knowledge very easy to follow, because my brain has its own way of doing that and it doesn't readily adapt to other ways, it would rather keep mapping new bits onto what it's already got, even if there might be a better way, unless it can clearly see that it's better.
But all in all, I guess it might do a bit of good here and there. I wish they taught propaganda studies and critical thinking in schools as part of the core curriculum.
So, the video gets my qualified approval. As for whether or not I'd dare to apply my knowledge of propaganda to the things I currently believe, AFAIK I don't really believe anything in the first place. Sometimes I see unscientific, emotive drivel that seeks to promote certain views akin to my own, but I usually know it's drivel, and I tend to think "I like the sentiments behind that but to me it's a very flawed way of expressing it." Other times I see scholarly work that has no axe to grind, backs up any assertions with externally-verifiable evidence, uses arguments that make clear logical sense, draws only tentative, qualified conclusions, owns opinions and speculations as what they are, and doesn't try to sell the reader anything, and I much prefer that kind of stuff, though it's often very complicated and takes a lot of hard work to fathom it all, and sadly I don't always have the time or the inclination to bother.
