I appreciate the feedback. Once I respond to people's objections, I'll be on my way.
This is (obviously) your prerogative; however, I would ask that you give it a bit more time than that. I'll just be blunt about why: you need LessWrong or something like it.
Okay, I know how annoying it is to be told about your own psychology by a stranger, but here goes. Your stated opinions, while extremely interesting and clearly well-educated, are of a form that makes it apparent you're starting with a bottom line and working upwards to arguments. That is, in the particular case of polyamory, you seem to be starting with annoyance at polyamorists and, as orthonormal implied, throwing out plausible arguments to see what sticks. The ethic of this community is to use rationality to become right rather than prove ourselves right. We don't always succeed at this, but we try.
Consider a thought experiment.
Think of all the hundreds of opinions you have on various issues and fact questions relating to science, public policy, economy, ethics, culture, sexuality, etc.
Realistically, you are dead wrong on at least one of those opinions (just like you know everybody else is). If you can't accept that as likely, I give up.
But you don't know which ones are wrong. Also, your brain is really terrible at telling you which ones, because it has dozens of (largely opaque) reasons for keeping its current beliefs. It only looks for confirmatory evidence. It likes stories better than statistics. It fears the social stigma of changing your mind. Perhaps worse than anything, the smarter you get, the better you get at rationalizing your bad ideas to yourself! I could go on, and on, and on...
Our community is pretty good at digging up those biases, exposing them to the light of day, and challenging you to question opinions previously held which might have been influenced by them. If you can do the same for others, the mutual benefit redounds to the favour of both.
So if you just want to convince people you're right, you should indeed leave. If you want to try to be more right, stick around and keep talking. That is why I am here (I'm a relative newbie). I want to be right about all those issues. It's an ethical question. And so far I have found nothing better than LW, for all its flaws.
I agree that we all need what you claim LessWrong wants to be, but I don't think I'm retreating in any way from having my assumptions scrutinized. If anything, the problem is the opposite one, most the replies haven't identified the key points on which my argument turns or their weaknesses, instead they've largely seized on what I think are irrelevant or incidental points, basic misunderstandings or just jumping to odd conclusions. I don't think my arguments are insincere attempts to see what I can make stick, I intend to defend them as best as I can &...
Many of us are familiar with Donald Rumsfeld's famous (and surprisingly useful) taxonomy of knowledge:
But this taxonomy (as originally described) omits an important fourth category: unknown knowns, the things we don't know that we know. This category encompasses the knowledge of many of our own personal beliefs, what I call unquestioned defaults. For example, most modern Americans possess the unquestioned default belief that they have some moral responsibility for their own freely-chosen actions. In the twelfth century, most Europeans possessed the unquestioned default belief that the Christian god existed. And so on. These unknown knowns are largely the products of a particular culture; they require homogeneity of belief to remain unknown.
By definition, we are each completely ignorant of our own unknown knowns. So even when our culture gives us a fairly accurate map of the territory, we'll never notice the Mercator projection's effect. Unless it's pointed out to us or we find contradictory evidence, that is. A single observation can be all it takes, if you're paying attention and asking questions. The answers might not change your mind, but you'll still come out of the process with more knowledge than you went in with.
When I was eighteen I went on a date with a girl I'll call Emma, who conscientiously informed me that she already had two boyfriends: she was, she said, polyamorous. I had previously had some vague awareness that there had been a free love movement in the sixties that encouraged "alternative lifestyles", but that awareness was not a sufficient motivation for me to challenge my default belief that romantic relationships could only be conducted one at a time. Acknowledging default settings is not easy.
The chance to date a pretty girl, though, can be sufficient motivation for a great many things (as is also the case with pretty boys). It was certainly a good enough reason to ask myself, "Self, what's so great about this monogamy thing?"
I couldn't come up with any particularly compelling answers, so I called Emma up and we planned a second date.
Since that fateful day, I've been involved in both polyamorous and monogamous relationships, and I've become quite confident that I am happier, more fulfilled, and a better romantic partner when I am polyamorous. This holds even when I'm dating only one person; polyamorous relationships have a kind of freedom to them that is impossible to obtain any other way, as well as a set of similarly unique responsibilities.
In this discussion I am targeting monogamy because its discovery has had an effect on my life that is orders of magnitude greater than that of any other previously-unknown known. Others I've spoken with have had similar experiences. If you haven't had it before, you now have the same opportunity that I lucked into several years ago, if you choose to exploit it.
This, then, is your exercise: spend five minutes thinking about why your choice of monogamy is preferable to all of the other inhabitants of relationship-style-space, for you. Other options that have been explored and documented include:
These types of polyamory cover many of the available options, but there are others; some are as yet unknown. Some relationship styles are better than others, subject to your ethics, history, and personality. I suspect that monogamy is genuinely the best option for many people, perhaps even most. But it's impossible for you to know that until you know that you have a choice.
If you have a particularly compelling argument for or against a particular relationship style, please share it. But if romantic jealousy is your deciding factor in favor of monogamy, you may want to hold off on forming a belief that will be hard to change; my next post will be about techniques for managing and reducing romantic jealousy.
