EDIT: Ratbastid beat me to it...
(I was taking my time writing)
Hrmm, rr1024...methinks you need to get to know Ratbastid a little better before spouting off like that, mate. He, along with Lurkette and StellaLuna, are in one of the most admirable polyamorous relationships I've ever seen. There are a few other poly-configured folk here on TFP who are also bound to chime in on this thread (I am not one of them, but I respect them).
What has been your personal experience, to lead you to the opinions you stated earlier?
