Long post!
So I saw a thread on FP not too long ago and I want to air my opinion on it.
Polygamy has been in existence since creation, and invariably will continue to exist under the guise of serial monogamy. Since a man is only entitled to one woman under the law.
The reason I exist is because my mum married into a polygamous marriage, same for many of us on this platform.

Why you think polygamy will not work?
1) I saw some funny comments on FP regarding polygamous men living a solitude life at old age, my brother the only reason a man will grow old to live in isolation away from the love of his wive(s) and kids at old is age how he treated their mother while he was still agile. If you dont want to be a wretched old man start taking good care of your wife. This has absolutely nothing to do with polygamy. Some men are just outright irresponsible.
2) you feel the children will not love themselves; this is not true as well. My grandfathers children are so close knitted that an outsider will think they slept in the same womb. Your duty as a man is to make sure your kids have a good relationship with one another right from their young age. This will eliminate or at least reduce the negative influence that their mothers might want to have on them regarding their step siblings.
3) maybe expensive? Generally depends on your taste of women and the number of kids you have. If you think polygamy is expensive you might as well try to be a serial monogamist. With polygamy you're sure to be spending your money on your wives and kids not a random side chick(s).

Why you might want to consider it;
1)Polygamy comes with openness of mind, you're at peace with yourself as a man because you wont be sleeping with a random sidechick but a woman that is also your wife. You dont have to be extra careful around your wife because you're cheating, you're as well married to the other woman.
2)You dont have to live in fear of your first wife because the second or third wives are entitled to as much right as the first. There are many married men raising kids secretly outside their marriage with a sidechick, with polygamy you get to raise your kids together even if their mothers dont stay in one apartment with you.
3)Polygamy could come with more fulfillment for a man. The first wife is a good cook but doesnt like sex, the second fulfils your sexual desires grin what a life cheesy if one is I'll mannered, you can find peace with the one with a better attitude. This plays out a lot in monogamy, your wife is sh!tty? You find peace with your sidechick.

The reality is only a few men will sincerely desire to be with one woman I.e marry one woman and not cheat on her through their years of marriage.
With what I read online everyday regarding cheating on the part of men, then I can say that serial monogamy is the new polygamous system.

There are many good mannered marriagable women that have been relegated to sidechicks, or very unfortunate when it comes to relationship matters, polygamy would make them a wife if the man they are with is open to polygamy and they are too.
Monogamy doesnt automatically means you will be happier than people in polygamous marriages. A woman could be more happy as a second wife than be an only wife of a community pen!s.

The bible prophecy is upon us, which one will it be for you? Polygamy or serial monogamy?
