For a start, whatever these psychopaths are saying about following "natural selection", that's not what they're doing. They are instituting their own kind of artificial selection — trying to give what they see as Darwinism a "helping hand". This is no different from what Hitler attempted with eugenics, which was based not on "random mutation and natural selection" but on the kind of artificial selection that dog-breeders (for instance) have been doing for centuries. All this article shows is that many people don't understand what Darwin's theory says (and have probably learned what they "know" from creationists — who consistently get Darwin wrong).
he author of this article, also seems to fall into the trap of somehow associating morality (or lack of it) with Darwin's theory. Unfortunately for morality, scientific facts are not amenable to opinion. The science is either true or false. Creationists are fond of saying that Darwin's theory leads to immorality, which, even if that were the case, has no bearing whatever on its scientific validity.
All this article shows is not that Darwin's theory has somehow been detrimental to some people's morality, but that some people are appallingly ill-informed about it. The fault lies squarely in the lap of education, and illustrates perfectly why evolution should be part of the primary school curriculum.
One last thing: citing Ann Coulter in support of your argument is, to put it mildly, ill-advised.
