Racial Reality in Hurricane Katrina

I found an article written by journalist Steven Sailer for VDARE.com, Steve Sailer is best known for his writings on IQ, Race issues and Politics. All of which he tackles in this rather controversial article about the racial reality from Hurricane Katrina.

The article is a bit controversial as it states that the probable mean IQ of an African American in New Orleans is more than likely to only be in the high 70's. This statement in itself is startling as it is painting many people with the same, aparently mentaly challenged, brush. As I carried on reading the article I was to be surprised again by another statement about the superdome organisation that Sailer put forward; 'poor Black people seldom cooperate well with eachother because they don't trust other Blacks much, for the perfectly rational reason that they commit large numbers of crimes against eachother.' There are other such statements in the article which both shock and astound for they seem to be hugely racist and a major generalisation of a people. The way he describes African Americans seems to be along the same lines that the slave masters thought of their slaves, Three Fifths human.
In a way I am not surprised by this article as through research I have discovered that VDARE has been branded as a 'hate group' although they say that they are just airing the views of anti-immigration.
A slightly amusing fact about this anti-immigration magazine is that the founder is actually British and emigrated to America. Slightly warped really.
