Gosh, out sick for a couple of days & look what happens. Hee hee. Thanks, y’all.
Testy -
I agree wholeheartedly that a stable, longterm relationship is best for children, and that it would be A Good Thing if no one without such had children.
However, I’ve gotta totally disagree when it comes to BANNING people from having children. For one thing, I don’t see anybody jumping on the bandwagon to ban couples from having children until they’ve proven their stability - and with today’s divorce rates, monogamy sure as hell ain’t no guarantee of stability.
For another thing, there is ABSOLUTELY NO EVIDENCE[sup]1[/sup] that intended-longterm-poly-r’ships[sup]2[/sup] are any less stable than standard marriages. Yeah, I know, stoid ‘believes’ that they are. Everybody has tried (or knows someone who’s tried) some sort of open relationship thing & it hasn’t worked - so obviously it’s less stable. Uh-huh. And there aren’t any gays with longterm r’ships either, y’know - everybody knows they just screw around.
Aside from which, as always with these sorts of grand ideas, it just ain’t practical. What about people who have kids AFTER they form a r’ship? Are ya gonna sterilize them all just to be sure? Or force abortions if they accidentally get pregnant? Or just steal the kids under the pretense of ‘unfit environment’?
What about a single parent who finds a poly r’ship? Will they be forbidden to join the group, because it might not be stable? Shall we put the same restrictions on mono marriages? Fine, go ahead, get widowed. You can’t remarry till your kids are grown, so ya better just like it. (Or maybe we should only apply these rules to divorced single parents - after all, they should have done better the first time, right?) Perhaps we should apply all of these rules to dating by single parents, too!
I think you get my drift. 
Got news for you, folks. A lot of poly people have kids. Doesn’t hurt the kids one damn bit, in fact most of them love it. The polyamory.org PolyCons have had ‘kids panel’ sessions for the last several years - the biggest problem the kids have (surprise, surprise) is dealing with outside pressures (from other kids, bigoted neighbors, school admins, etc.). The ‘kids panels’ give them a chance to exchange techniques and ideas for dealing with those sorts of problems - and a chance to tell parents how to help.
IMO (with no evidence whatsoever, just based on reading & discussion), I think poly people are less likely to have kids until they’re sure they have the stability to support them. That’s one of the bennies of being outside the norm - you feel less pressure to obey the rest of the rules as well.
Not to mention that we’re well aware of the possibility that poly is less stable & any thinking person (which most poly’s are[sup]3[/sup]) would be very careful about bringing kids into an unstable r’ship.
Now, if you can grant me the assumption (at least momentarily) that a longterm poly r’ship is just as stable as a mono r’ship, I think you can see obvious advantages for kids. More parents = more time for kids (often including one parent able to stay home without the income sacrifice that causes for mono couples). More parents = more likelihood that a kid can find a parent s/he can comfortably relate to & go to with problems (might even be a different parent for different problems). More parents = less stress on parents (if you’re too stressed to deal with the kids, you’ve got more options for help). So on and et cetera.
In summary, while I think Stoid’s intentions were good, I think her implementation sucks. 
[1] There really isn’t much evidence available AT ALL on poly r’ships. I read recently of someone that had just completed a 20 year study on poly r’ships. Unfortunately I read it in a print journal & haven’t been able to find it online - AND I lost the name & such details. (Argh!!!) That is the only study I’ve heard of that has followed poly r’ships for any length of time. As far as I could tell from the brief summary I saw, that study shows no real difference in stability between equivalent mono & poly r’ships (see 2).
[2] One of the problems in this discussion is that many polyamorous relationships are never intended to be longterm by the participants. While I agree that people in such a r’ship shouldn’t be having kids together, fact is, they generally don’t (accidents can happen, of course). I’d guess that most of you that have ‘tried’ poly weren’t really intending it as a lifetime commitment as much as a brief interlude or occasional fling. While I’ve nothing against that sort of thing, it’s not really fair to compare those r’ships with mono-marriages and then claim that poly is somehow inherently less stable. It would be like comparing a poly marriage (where everyone has committed to the long haul) and the average American’s dating habits - I guarantee if I did that, I could show that poly was incredibly stable compared to monogamy. 
[3] I’m not trying to make the ‘more-evolved’ or ‘superior poly’ play here, really, guys. I know it can sound that way, so I’d best explain. Since the cultural default is set to ‘mono’, that alone tends to strain the ‘non-thinkers’ out, because poly never occurs to them. By the same token, I’d say that most SDMBers are ‘thinking people’ as compared to Websurfers in general, which is due to the nature of the board and its natural filtering tendencies. Make sense?
