I figured anti-polyamory propaganda did not need annotations on LessWrong. It's telling that all but one reply took it as something which needs to be suppressed/counterargued, despite me calling it propaganda and saying it was interesting as an example of psychological tricks people pull. No one here is going to be taken in by this. I would not have posted this on facebook or another more general audience site.

I did not feel like writing it up in any detail would make a great use of my time, the examples to use for future pattern matching to are pretty obvious in the video and don't need spelling out. I just wanted to drop the link here because I'd found it mildly enlightening, and figured others may have a similar experience. I take the negative feedback as meaning content people are politically sensitive to is not welcome, even if it's rationality relevant (resistance to manipulation tricks) and explicitly non-endorsed. That's unfortunate, but okay.
