Sure, mods, not admins!
I do realize I'm stepping on your toe again, but I do think there is a dominant line of thought here on what we consider good poly practice, with just minor variations.
As an example of valid poly that's frowned upon here, take one-penis policy. I bet there are communities which would consider it a totally valid way, and wouldn't make people to try see the light and make things fair! I could make up half a dozen convincing arguments!
I'm sure there's more, but we're just fish not seeing the water
Okay. My point is that the mods/admins have not "arrived at a dominant line of thought." This board has been around since 2009, and we've had 10s of thousands, if not hundreds of thousands of people stop in, some for a day, some for years. And dozens of books have been written on successful polyamorous practices in that time period. (When I started polyamory in 1999, there was one book, The Ethical Slut.) Everyone who has come through here in those 16 years has influenced the evolution of a workable way to practice polyamory. It wasn't forced on anyone by the admins or mods. We just make gentle suggestions.
You could say we were the pioneers of how to do polyamory in a way that actually worked. The first founders of polyamory thought the best practice was to have a MF couple, who would recruit new lovers to come live with them, and everyone had to be romantically, preferably sexually involved with each other, resulting in a rather large household, or intentional community. Obviously hardly anyone does that anymore. It is idealistic, and not practical. It just doesn't work, in the huge majority of cases. It leads to all kinds of problems.
One-penis policies are more of an unexamined misogynistic way of doing things (in most cases). If it comes naturally, fine. If it is being imposed on a woman who would prefer two or more penises, it is coercive, which is wrong (unless there is a D/s understanding).
I guess I just bristled at the idea that the admin here has declared "one narrative/line of thinking," when it's more just doing what actually works, and can lead to healthy happy, hopefully long-lasting relationships, that honor and respect everyone. I mean, why do what doesn't work, what makes you unhappy, unhealthy, and/or leads to breaking up?
