@kuvasz,
That may be a good idea, Kuvasz. But how will you select those to be eliminated?
I am sure you are familiar with the famous quote by Justice Oliver Wendell Holmes.
If you really use conventional cognitive measurements, you should be prepared for the extimination of at least five million African-Americans.
But, that would really affect BO in his re-election drive in 2012.
That is why Eugenics is off the table!
