The title of this post is actually very offensive! Mostly because of people who DO actively try to convince people that being happily monogamous is somehow evolutionarily or morally wrong.
This smacks of predatory behavior and is rarely, if ever successful. I know there are unbalanced or deluded people out there who think they can "convince" others to leave behind lovestyles that they believe are not healthy or right but this practice won't have lasting results unless the person was actually choosing to remain monogamous because of the belief that polyamory is wrong. Even then there can be a period of intense grief, fear and emotional pain that is horrible to watch. If I love someone I don't want to put them through hell even if they might be happy afterwards.
It reminds me of people who will go into a field and try to round up the most resistant horse in the field when the others are crowding around begging for attention!
Personally, I live my life openly poly and if like minded people happen to notice then we have a great conversation which may or may not lead to something more. It seems like a waste of time to try to convince someone who isn't poly minded when there are many many others who are already looking for this type of relationship.

I found it offensive because it is an accusation that is leveled at poly folk who live openly by people who are afraid of anything that challenges what they believe to be right and proper. I am not trying to recruit people or destroy monogamy by being happy in a polyamorous relationship. I do realize, however, that I am in the minority in my belief that both monogamy and polymory are perfectly natural lovestyles for humans.

Also it is very offensive to me when people DO attempt to recruit happily monogamous people to the poly lifestyle. I notice this happening more and more in the pagan community and in the LGBT community. So I wasn't just objecting to the language of the question but also to the idea behind it, if that makes sense. It is reverse discrimination to insist that monogamous people are jealous, insecure and childish. I have found happily monogamous people to be very secure, mature and willing to entertain any notion their partner may have up to sex with another partner. To make a choice with a partner to be monogamous rules out cheating...or at least it should! This is why I always remind people that the struggles we poly folk face are no different than the struggles mono folk face.

I am sorry I wasn't more clear about why I was responding...I never intended to imply that you were meaning to be offensive or oppressive. In an ass-backward way I was actually agreeing with you that the practice of trying to recruit a monogamous partner to polyamory rarely works and can actually be very damaging to them emotionally. You are totally correct that asking the question isn't offensive, if I had found it offensive I would have opened a private dialogue with you to see if I was being unreasonable or whether you were actually meaning something else entirely.

What I meant to say was the IDEA of 'recruiting' people to polyamory is offensive and I misspoke.
The question did catch me off guard but that is because of personal issues I have dealt with in my own life but I should have made it clear that I didn't find your post to be offensive. Thank you for being very gentle in your response when I know you might have felt a bit attacked by mine.
