Most people readily accept that dogs can be bred for aggression.
The pit bull, while often charming and pleasant, may more easily transform into a killing machine under the wrong circumstances than the playful Labrador, or the phlegmatic St. Bernard.
Is it then really much of a stretch to imagine that humans too, could be so bred?
And if a human breeder could thusly breed humans, even in theory, could we not bring ourselves to envisage that Nature herself may have bred certain populations of human beings to be as aggressive and unpredictable as the pit bull?
Ladies and Gentlemen, and others, I think you know of whom I speak.
