A very well thought out piece. I do think that there's a lot of anthropology that indicates that monogamy isn't a default human state, but rather a sociological one, but that also doesn't mean that people can't choose it for themselves if it makes them happy. My issue is that most people (including myself for many years) didn't really realize that they had any other options because it's so socially proscribed. If ENM were more socially acceptable, I'd have no issue at all with those who want to opt for monogamy choosing it - but most people don't truly choose it. I think that's the point that many people are trying to make, but I also get how it can come across as holier than thou.
