Cousin marriage is a problem in some countries. It is a very cruel practice affecting children as it does. The serious negative effects can pass down several generations and more.

Paul 1405,
Why would the Lebanese department of public health in conjunction with the American University be conducting long term, inter generational studies of the effects of consanguinous marriage among North Lebanese Muslims?
It's long been known that the Muslim problem in Sydney stems from the tribal background of the Lebanese migrants to that city, that even though other capitals have Lebanese populations they don't have as many Muslims from Northern Lebanon.
The Arabic tribal customs and marriage strategy cause genetic damage to their offspring resulting in among other things low intelligence and it's attendant symptoms such as poor impulse control.
You can go and read the research papers yourself, Israeli scientists are also working on correcting or breeding out the genetic defects caused by inbreeding in Ashkenazi Jews.
European descended people don't have these problems because of a strict prohibition of incest and consanguinous marriage, it's not discussed because it's not an issue...and please nobody bring up the trite example of the royal families, if ever there was an example of the genetic cost of cousin marriage it's in "The Lost Prince".

Paul don't be stupid.
Note Lady Deech's comments in on the beach's links.

You obviously have no idea what you are going on about.
Have you no idea what the costs are to raising handicapped children ?
The staffing of the special schools is very difficult and needs staff
of a caliber that is way above normal schools.
The costs for the lifetime of these children is massive.
Remember they will get the disability pension for life and need many
kinds of support from parents and government.
Have you never seen the 80 year old woman taking her handicapped
50 year old child shopping ?

You do not know you are alive !

The real problem is that the Arab & Pakistan & Afghanistan people
will need hundreds of years of never marrying cousins to breed the
problems out of their nations.

When I first read that I found it horrifying. The problem is so widespread
in their populations that the costs to our medical and welfare systems
might well become a problem for our government.
Additionally we should examine those in gaol to see if there is an IQ
problem there.
However generally people with an IQ problem are very aware
of not committing crimes or breaking the law in any way.
When they do it is generally because they do not understand that law.
In different cultures it could be different.

Given the attitude to women in moslem communities those with limited
understanding might think any women fair game.
It is those with mild intellectual handicaps that are the risk.

The problem is that gutless federal governments pursuing political populism have been seduced (coerced?) into allowing the diversity tail to wag the immigration policy dog.

Why would any government direct Immigration bureaucrats to prefer immigration applications from Pakistan for example to other, eminently more suitable applicants? That Department and the Department of Foreign Affairs would be failing in their duty if they were not advising the government of the risk of importation of toxic, incompatible political systems, traditions and values.

Why is Australia volunteering to rescue and give a home to claimed refugees on the other side of the world?

Australian politicians travel far too much and they like to look good internationally. There is always that hope of a UN job - that rarely eventuates. Or being made to feel important by the US State Department, in exchange for agreeing to take that pesky nuke waste that costs Obama heaps to keep and cannot be hidden away somewhere no matter what.

There is no doubt that regardless of attempts to sweep everything under the carpet as usual, mass immigration and that 'diversity-Australia-has-to-have' that results in unsuitable migrants will be key issues with the electorate in the coming federal election.

OTB,
Yes, it comes back to one question, what do immigrants from Africa and West Asia have that we can't get anywhere else?
The obvious answer would be nothing, either all people are equal or they're not, if we're getting into some sort of discussion about intrinsic racial qualities then isn't that taking a step down the road to Auschwitz?
