Pretty much.
Also, under the circumstances I’m giggling like a fool over the use of the word “clusterfuck” earlier in the thread. 
And racial intermarriages, religious intermarriages, homosexual relations, stay at home dads, right? It’d be okay if anyone said those were “like kids playing house. It’s immature, and self-absorbed, and (in my opinion), it’s obnoxious to expect people to take it seriously”, because the majority doesn’t practice them?
Amount of adherence in human society of a particular lifestyle or relationship type has no relationship to its practicality or need for respect. After all, we could just as easily have said, 50 years ago, “if it worked for the majority for women to be treated as equals in the workplace and have their own jobs, it’d be practiced by the majority”.
What people practice in their personal lives typically has a whole lot more to do with cultural and social norms than what is practical, fair, or admirable.
Societal conditioning and religious prohibition are significant impediments to poly being accepted, so I don’t think the bolded part of your comment is true at all.
I agree with the second part.
This kind of comment:
Really makes me wonder why anyone EVER engages Dio in this sort of converstion. Flat out, he is right, and you are just wrong for even thinking otherwise.
I wish people wouldn’t even answer him. Why do you need to convince him? All it does is hijack the thread away from an interesting discussion - what the OP in the other thread should do, if anything.
Why do you qualify your statement with “sex-related topics”? It’s the same pattern every single time regardless of the topic.

This beautifully describes your typical “contribution” to a thread. Just whose pet troll are you?
Hotty toddy?
When and where? Do you want my e-mail address? You do have a hen outfit right? I only ask now because, well, we’ll get to that later ok?
Why are your feelings hurt by random assholes on the internet?
I suppose. They are the equivalent to leatherbois of the polyamory set. 
My wife and I joke about how we wish we could find a woman who wanted to be a stay at home Mom so that we could go be career people.
Not at all what I was getting at. I myself am not polyamorous and yes, it’s true that his opinion doesn’t figure as much into my life as the opinions of people I know personally. However as someone who is in a lesbian relationship I can definitely relate to how it feels when people hold the attitude of “X kind of relationship is not valid.”
To be fair, Diogenes has clarified his stance as being “because it’s an X kind of relationship they have to do more to prove their commitment than a monogamous couple would.” That still reeks of unreasonable bias.
I was responding specifically to Shagnasty’s contention that he saw those relationships fall apart all the time–I was trying to express that their perceived or actual failure rate had nothing to do with their perceived or actual legitimacy as a relationship, and you seem to have taken that the opposite tack.
I’d agree with your latter two paragraphs in toto, considering I’m the polyamorist who got into the initial tussle with Dio in the linked thread. =P
I am comfortable with Dio’s unreasonable bias. If you want to fuck a lot of people, don’t get married. Then if you bring two women/men to a party, people will just know you’re a tool, and not have to dance around pretending you’ve got an acceptable alternative lifestyle.
I do see one thing harmful about polygamy: I don’t have any hard data on this, but it seems most of these relationships are one male, multiple females. This can’t really work on a society wide scale, because there are going to be a LOT of unhappy, single men out there who won’t be able to find partners.
SecretaryofEvil was the voice of reason in that thread, but that doesn’t make Dio wrong.
[advocatus diaboli]Your fears about your permanent singleness, however justified, do not grant you a mandate to bar some woman from making her own decision to be a party to a poly relationship with a man she finds desirable, simply in order that you might have a mathematically better shot at her.[/ad]
I’ve always said that if you’re a hot nymphomaniac, you can’t go wrong by keeping and grooming a stable of well off nerdy guys who wouldn’t get laid otherwise.
pfffft. That’s what everyone says. But they complain bitterly about the grooming.
Let the homos have them.
Though in all seriousness I hope you realize that this has been the rule throughout history and not the exception. Men are less likely to reproduce than women are.
