They generalize too much and are boring. I wouldn't continue talking to them.
If I had to respond, I'd point out how many don't get jealous. Many aren't possessive either. For one, you have religious people who are just following their book/s. Monogamy can be about morals rather than fear, protection and security (against being alone or STDs), etc.. The maybe just chose to only be with eachtoher as well. Plus, possessiveness comes in degrees. It's highly subjective..but then again, if you look at the definition of the word, it's clear that many people in monogamous relationships don't fit that at all.

whole big heap of blanket statement right there! personally capable of monogamy, NOT possessive, never had occasion to be jealous in my life. it's an emotion i've never even developed lol. they should stick to what they know not what they can make up.

That would be what we call generalizing. It's rarely a very insightful or intelligent thing to do.

That's not necessarily true. A lot of monogamous people are very secure in their relationships. Meanwhile, there are also a lot of polyamorous relationships in which one or more of the people involved are extremely possessive and get jealous when one of their partners gets involved with someone else, even though that's kinda the point of the relationship in the first place.

Untrue. I am a monogamous person, and I am definitely not possessive or jealous. If a person is not on the same "wave length" (as far as monogamy goes) as I am.. I simply think we are mismatched and move on, but would still be friends with that person, and never judge them for their choices.. everyone is different and thats ok!

"Cool story, bro"

All people are jealous and possessive in varrying degrees and aspects.

When those two traits are negative (sometimes they are positive) they stem from insecurities. An insecure polygamous person will feel the need to control his partner's ambition and how much he expresses his love to others by occupying their time too or any other means.

Jealousy and possessiveness is not only evident in sexual preferences.

i think its between commitment and not wanting commitment.

How many successful polyamorous couples do you know?

Some are some aren't

maybe they are just in love?????? radical concept i know lol

I think monogamous people are normal.

I would tell them to shove their opinion up their ass. 🙄 Neither Mono or Poly relationships are bad. Both have their ups and downs. Shitting on someone and how they love is so immature.
