Thanks Foxy for that link.
The problem is now much worse than the articles I first read.
The major factor that makes it worse is that it has been going on for so many generations.
Having seen the problems with behavior that can result it is not surprising that
organisational behavior such as we see from ISIS can result.
The lower average intelligence of the community also I think would result in a lower
standard of living for the community as a whole.

The only way that it can be stopped is for the government to declare all cousin marriages
to be null and void. As the article suggested if all government support ceased it might
change their mind, but it would be cruel to the children.
A real case of being cruel to be kind.

Banjo,
No I have not seen any statistics. The NSW Health Dept got onto it when they
noticed the high number of children born at Auburn hospital with genetic defects.
They sent a genetist to do a study there and she went and interviewed the mothers.
In almost all cases they were married to their cousins.
Her report was tabled in parliament never to be heard from again.

The big question is how much is this now costing our health service ?

The American University in Beirut have studied consanguinous marriage and released their findings:
http://online.liebertpub.com/doi/abs/10.1089/gte.2007.0093
I had that paper in full on my old computer but I've lost my library card and I'm not paying $50 to look at it again. If you've got a university or state library card or know someone who has you might be able to get it from one of the U.S universities, they're usually all linked once you join a state library.

"Consanguinity is a deeply rooted social trend among one-fifth of the world population mostly residing in the Middle East, West Asia and North Africa, as well as among emigrants from these communities now residing in North America, Europe and Australia."

All part of that diversity-we-have-to-have that is the darling of the culturally-cringing leftist 'Progressives'. The 'Progressives' neither recognise nor care about the negative consequences of their policies.

Putting the general aim of non-discriminatory immigration ahead of the common good and future of Australians is worse than foolish, it is reprehensible to put the Australian community at risk of what happened and continues to occur in (say) Rotherham, UK.

No-one in government has ever offered an explanation why immigration is perversely preferring migrants from countries and regions with political systems, cultures and traditions diametrically opposed to our own. To do that, Immigration bureaucrats have to refuse migrants from much more suitable backgrounds and with desired education and skills. There are thousands of highly suitable young tradespeople in Northern Europe, Ireland and elsewhere who want work and a fresh start. So why not take them?

Dear Nathan,

You told ConservativeHippie that: "You once again, take on the "we are perfect" approach. Like Yuyutsu did, will then very easily target the United Nations":

What are you referring to? I do not recall saying that "we are perfect".

As for the United Nations, they are a criminal organisation because besides being useless they among other things:
1) Helped Saddam Hussein obtain weapons against his own people.
2) Supported the massacre of Tutsies in Rwanda.
3) Supported the murders and rapes in Darfur.

I happened to learn about it by watching the movie in http://www.unmemovie.com/

Jay,
I have a state library card but I am not going to the city any time soon, although
it might be possible to request it on line.
However I don't think I need more than I already know about this problem.
One measure the government could do is at overseas embassies they could test couple's
DNA to see if they are related.

Actually thinking about it. it probably accounts for the generally lower standard of living
and the somewhat poor treatment of women in Moslem countries.
I do not pretend to be knowledgeable in this subject but it does have some logic to it.
