I think a proper explanation is that Creationists tend to select other Creationists, perpetuating this ignorance across generations. In other words, in the eyes of some females, it is evolutionarily disadvantageous to actually have a firm grasp on reality, while in the eyes of intelligent females, that same trait is evolutionarily advantageous. Consider it Genetic Drift, where traits (e.g. intelligence) can have natural (or in this case, self-imposed) variability, and since there are both males and females that possess one trait or the other, lack of possession of intelligence isn't really a disadvantage when it comes to reproducing.
In other words, stupid people will be able to breed with other stupid people, so that stupidity will not be eliminated by natural selection alone.
So disruptive selection will one day make 2 different species... AWESOME
