> "polyamorous people have the same issues as monogamous people…. sort of."

Yeah, poly people mostly have the same problems mono people do: jealousy, insecurity, need of attention, fear of being put apart or left... because those are human fears, hence universal.

Besides, those problems are "multiplied" by any partner included, so the more partners, usually the more possible problems. OTOH, the more partners, the more chances one has to receive love, attention and understanding (while in a mono couple, there's only one partner that can give you those things; and if s/he doesn't, nobody else will).

Thus it doesn't make sense talking in term of mono opposed to poly: no way is better or worse in itself, you just have to find out what works best for you.
