Here is a video by youtuber Jess D, wherein he talks about humanism and polyamory. I think the video is generally good, although I have some minor issues with his discussion about whether polyamory is “natural” or not. This has mostly to do with my pet peeve of making a distinction between “natural” and human actions, but I also believe there is some equivocation going on there. Otherwise, it’s a fairly good introduction to polyamory from a humanist;s point of view, and worth the 14 minutes or so.
enjoy!
