Many societies that have a god or gods allow polygamy, not just Islamic ones.
Monogamy was socially developed by two main considerations. The need for a father to support his offspring and the need to restrict the chance of inbreeding.

For me in particular,
Polygamy = a most definite and adamant NO.
Abolishing anything - Yes, IF entails the eradication of ALL influences/interferences of Religions on Society at large.

Relationship is a social contract. Participants conduct themselves according to mutually agreed laws and agreements. Breaking such rules and agreements means violating the contract. For example there are already women and men with multiple partners and all of them agree to this arrangement. Church and state brainwashed people into thinking that what they define as marriage, family, and relationship is the only correct one that is why people who do not follow these imposed rules but instead follow their heart are made to suffer. The time has come to correct our brainwashed brains.

A post-christian society is one in which fewer and fewer people believe, but the christian values are so imbued that they live on. I used to think a community of non-believers would take to behaving as our fellow large mammals. Not the case.

The two could not be less related in my mind. If anything, polygamy is more closely tied to religion (see Mormonism and most of the Old Testament).

I feel like it's 100% based on personal preference and has nothing to do with religion or lack thereof. Some people just want one partner, some people want many.

Ask these women

I voted yes because I personally think being an atheist makes it easy to look at everything with an open mind, without pre-conceived notions.That's me. However I have seen many dating profiles where religion is important to them while they preferred non-monogamy, BDSM and more.

Being atheist isn't something that can be subjected to definition other than that of having rejected gods/theology. There is nothing else to be added or subtracted that could be reasoned to qualify one as a 'true atheist'.

A true 'Atheist' is spoken of as a proper noun, as a label or title most often rather than an adjective merely describes one's state of mind or attitude.

The trouble with the former conception ( more popular) is as soon as you label something as a noun, ambitious, self-important prigs begin to dream up criteria and establish their own petty orthodoxies; umbrella intellectual fifedoms over which they deign to preside, claiming superior judgment over who is or isn't "TRUE".

As to polygamy; it is therefoe impossible to draw any consistent relationship between it and the atheist mind set one way or another. They aren't related any more or less than any other thought on that narrow basis alone.

Polygamy in our time and place in history is flawed like every other social practice/institution within human societies by the simple, pathogenic common denominator of male dominance. Anything dominated by males is poisoned from the start.

No. Men who intend to be monogamous cheat out of weakness. From losing an internal battle against innate feelings of attraction for the opposite sex. And it apples to both religious people an non religious people. If I had to pick a side, I would say atheists are better at this because they have more control over their minds.

I always thought Mormons had polygamy....why would you think we would?

The norms of human behavior come from our evolved heritage, religion merely takes what is there and gives the credit to the supernatural beings, because the priests who are employed in their name want them to have credit for everything, thereby getting more power and wealth to themselves. They should not be allowed to take credit for moral norms, any more than for making the rain fall. (Though they tried that too, because they could get away with claiming anything which people in the past could not understand.)

I see no correlation between being an atheist and being.... well, anything different than the general population. Being religious does not make one believe in certain morals or ethics, and I doubt that not having a religion telling you how to live will change your basic temperament. I would not want a polygamous relationship, period!

That's just silly I've been an Atheist my whole life and I would only be comfortable in a monogamous relationship I'm not condemning others who want to have polygamous relationships but I am a monogamist because that's how I feel

I don't think so monogamous lifestyle can be abolished. Sexual relationships come in different styles and it doesn't matter if a person is an atheist or religious. The great thing in a non believer community is that people try to be honest and clear about their sexual relationship preferences.
I was religious and now I'm a non-believer but I'm still feeling comfortable with the monogamous style and also I expect the same thing from a partner.

Here are some examples of sexual relationships styles and maybe somewhere are more styles.
Monogamous Relationships.
Polyamorous Relationships.
Open Relationships.
Long-Distance Relationships.
Casual Sex Relationships.
'Friends With Benefits' Relationships.
Asexual Relationships.

Zesty, we just have an arena where people can more openly discuss their proclivities and preferences. If such freedom existed outside of this site you would here more. There are communities where these topics are openly didcussed, but they are cloistered and guarded for the above reasons.

"Abolishing" anything sounds iffy. I think people are more likely to live and let live, without religion to teach them to be judgmental.

We are more open minded about desires of humanity. I have no problem with polygamy.

I've been a nonbeliever since I was a child but as an adult I am always monogamous. It's a preference on my part -- I put not judgment on those who choose to live otherwise. I simply cannot invest myself in more than one person at a time. And I doubt I'd be willing or able to share.

An atheist is more freely able to decide for themselves what life they want, monogamy, polygamy, etc. More what defines those positions resides in the society as a whole, and its attitudes towards interpersonal relationships.

Your question smacks of the idiotic belief that atheists have no ethics or morals.

I was an atheist for 25 years before trying polyamory. I reached a point where I decided that serial monogamy really hadn't worked for me and decided to try something different. So far it's been good for me except for those times when you get really into someone and get rejected because they just are not wired for or accepting of polyamory.

maybe in a few generations but maybe not. will be interesting to see

What does one thing got to do with the other?..... why do you think there is a correlation?

Just because atheists are in principle freethinkers and more free in principle to diverge from societal norms without concepts like "sin" in the way, doesn't mean we suddenly are polyamorous or polygamous (or licentious, or dishonest, or unfaithful, or whatever).

Personally I find serial monogamy difficult and frustrating enough to navigate without complicating matters further than they already are. It is a practical matter, and me not seeing any percentage in polyamory. Has nothing to do with my lack of beliefs in deities.
