It is all quite simple really.
The proportion of boys and girls born tells it all.

To see what happens when you change that look at China.
The one child policy resulted in testing if a fetus was male or female.
If female the decision was made to abort in many cases.
The result is many Chinese men unable to find wives.

Every time a polygamic marriage is undertaken it is one more man unable to find a wife.

It is that simple !
If you can't understand that then you are really stupid.

"Every time a polygamic marriage is undertaken it is one more man unable to find a wife."

You see Mom - it's not my fault! ! !

(and thank the Lesbians too for the relief!)

Do you seriously believe, Bazz, that all those harems would drop straight into your lap just because the government refuses to give them a piece of paper?

I do agree with Jaylex: governments should step right out of this whole business of marriage. Leave it for every person and every group one belongs to, to define or interpret for themselves what "marriage" is all about.

I said;

Oh well I was wrong, some people are !
The Chinese are suffering a number of social problems because of a
shortage of girls according to a number of reports I have seen over a
considerable time. Now I did not save the references, so go and look for them yourself.

One of the fundamentals of human nature is the need for a lifetime
partner. Even a lot of birds an animals cohabit for life.

That is just the way it is and saying it isn't is a detachment from reality.

In a normal community, about 105 boys are born to 100 girls. In some parts of China that ratio is slightly higher (but not all parts).

Something I have never heard a feminist mention is that the number of boys being born in many countries is falling, leading to a concern that this could be caused by pollutants in the environment.

However most polygamous marriages were initially amongst societies that had a shortage of men, often because more men were killed at a young age, normally through wars or tribal fighting.

I tend to think that polygamy has about as much chance of success in our society as feminist inspired de facto relationships.

They have buckley’s chance of success, and like feminist inspired de facto relationships, they are more than likely to lead to single parent families living off the taxpayer.

Vanna;
There is another factor which I have only just thought about.
With Poly marriages the gene pool that exists in a commumity
especially small communities contains a larger amount of close relative
genes.
That is something to avoid. The effects can be seen in moslem
communities in Australia and the UK where studies have been done on
cousin marriage.
The UK parliament was considering a law banning cousin marriage but
I never heard anything further on the matter.

Trav, you know quite well were I am coming from, and playing semantics does not help the debate.
I care not, about how consenting adults live their lives, and I respect those with religous or so called "moral beliefs". I ask what is your reason to deny two people who have a loving commitment, the right to have their being as a couple legally recognised.
It will have no affect on you or any person and individual, love comes in many forms, and is always beautiful.
