Why is polygamy taboo-ed?

You are assuming that there is one male and multiple wives in a polygamous relationship.  However, the converse can be true -- one woman with multiple husbands.  Indeed, it would theoretically be possible to have a polygamous relationship among multiple males and multiple females. 

In my view, the reason that polygamy won't work out in reality is because humans are naturally jealous.  Relationships will become strained over time as one or more spouses begin to feel neglected or less loved than their counterpart spouses, which will lead to arguments and ultimate breakup of the "marriage."  Of course, this can happen even in a monogamous marriage, but I think having multiple simultaneous romantic/sexual relationships create tension and discord.

Thank you Heaven! I agree with you, Sex is about being selfish. If you consider all the moments you spend in this life, then life it's not so short, your memory is and your desire to serve your selfishness.

How taboos develop is very complex and often difficult to explain.  Typically, there is some behavior or conduct that society (or some segment of society) wants to discourage.  Society's "leaders" then promulgate so-called "moral" standards prohibiting such conduct/behavior and inculcating in the population at large the notion that such conduct/behavior is destructive, anti-social or not socially acceptable.  Sometimes, there is some logical basis for discouraging this conduct/behavior, but over time, the logical reasoning is forgotten, and the only thing that remains is a strong bias against those who still engage in the taboo conduct.

Notably, social mores change over time, and conduct that is taboo in one time period was acceptable in the past or gains acceptance in the future.  Moreover, taboos are rarely universal, and certain societies or subcultures do not find the taboo conduct to be immoral or socially unacceptable.  For example, polygamy was acceptable during certain historical periods by certain groups (e.g., Mormons early in the history of the Mormon church, Chinese before Communists took over).  Even today, polygamy is practiced by certain subcultures even in the US, despite its illegality and lack of social acceptance.

Life is too short? False. It's the longest thing you do.

   Polygamy:

  Jacob Zuma ( president of South Africa ), as a polygamist:

He seems happy.

That's too ambiguous for me to understand especially when the word "love" is so vague? Or at least since "love" has a lot of different meanings?:)

Yes you are right sometimes it's difficult to separate love feelings from empathy and most of the times the critical point to understand this is when our personal interest getting involved and the choices we make around this. How we allow our emotions getting affected! and how we allow our selfs to interact love through personal connection.

Let's say for example that you see an old man sitting desperate somewhere , were it is obvious that he is lost and confused. Your buss is leaving in two minutes and you have no time to get more interest to find out what is going on. You have doubts in your thoughts: Does it worth to lose my buss for something it might be no serious or not? I believe this thought is the difference between someone who try to learn how to love and someone who is ok being empathetic independence from what is gonna be his final choice.

Someone who want to learn how to love doesn't think the necessary of the issue or the personal cost. He/She has already motivated him self with the right cast of mind. He/She is already prepared for these moments.

If we are ready to show love to a stranger then we are ready to love our life partner. We need exercise Trysts. People believe that love is a feeling that waits to be shown in the right moment, nonsense. People believe that love is only a emotion and has nothing to do with the way of thinking, no! Love is a way of living but we are not prepared for this kind of life, mentally.

We have more than ten times the chance to show our love in our 24 hours reality but we don't! There are always respites in our thought to hold us out of it! Personally respites for our selfs, beliefs, others e.t.c

...and not only respites! We have a strong selfie that bothers us all the time : I have to do this and then that, I must go there and then elsewhere, I have to say this , to organize my self for this, to program that...

Suddenly we have spent 12-15 hours of our day thinking a selfie routine and we are about to find a way to bring back for our selfs the lost energy of the day : food,entertainment,sex,sleep

Ring! Ring! The sun is rising, let's go from the start again. Were is love in our life's? In spare moments were we are not ready to interact or in rare moments we are prepare for.

Polyamory is a perfectly valid choice for those who choose that path. Is it the right choice for some people? No. Likewise monogamy is not the right choice for some.

Some people need to realize that their morals do not apply to everyone, and that someone can be a moral person even if their morals differ from yours.

And you need to take legal matters into account.

Okay, I'm pretty buzzed now so I'll have to reread this when I wake up, Bishop:)

Edited:

It seems as though you're saying what love is? You're saying that love is not soley emotional, that it is learned, correct? I think love is a personal experience one has with very few people. I don't see how a love for many strangers is possible, in my point of view, Bishop?

Bartenders...

I live in a part of the world polygamy where is legal, it possibly came about to ensure survival in a harsh environment.  I would suggest not judging it, evolution will eventually do its job. Western society is still influenced by male dominance, it is not exclusive to societies which practice polygamy by any stretch of the imagination. Women are unequal the world over to different degrees and I think change will come in its own time when individuals and systems reach a level of awareness which equips them for change.

Don't judge polygamy because evolution will take care of it?? That sounds like the process of evolution corrects moral injustices, so it sounds pretty absurd to me. Moral injustices require criticism in order for change to occur, in my view.

When the horse collar was invented, productivity increased because more acres of farm land could be put under cultivation with horses than with oxen. Women had been more involved with  planting and harvesting up to this point, but it was feared that the increased amount of strength required to work a team of horses vs. Oxen would cause an increase in miscarriages. In addition Men saw it as a way ole ay to secure property that they felt rightfully belonged to themselves and their sons, and the Monarch and ft he pope ı

I understand Trysts. It's impossible for the average human being to create a cast of mind that will include interactions ( Love ) with a unknown to his familiar environment. To imagine the difficulty it's more easy for us to go away from people we used to be together than to approach new ones. We are not ready for this kind of love or life and I don't really know if we will ever be but our purpose for this life does not stop in survival only and that personally gives me a motive to understand why. Some times I find it, some times I catch my self losing it, ignore it , but I feel it somewhere out there waiting for me.

I don't know much for Polygamy and its cause to contribute more in this discussion and I already feel that I typed words that it's unusual to be explained with letters.

I will tell this Trysts : Almost everyone in this world is responsible for his way of thinking and it's in our hand to make a difference in the way we want to live this life.

@Bishop: If "love" is defined merely as human interaction then we are speaking about two different things under the heading of "love".
