Oh well how do you explain how Hitler was defeated then? Clearly Nazism isn't the fittest is it? It perished.
The fittest system is one with good morals. Evolutionary speaking a society that cooperates is stronger than one that works by "law of the jungle"
Thus, when woodb01 posts this:
Hitler's National SOCIALIST "uber-man" or Aryans, or the "super race" are all based on crazy notions of natural selection. The National SOCIALISTS determined that Jews, the sick, the elderly, the disabled, etc., weren't as "valuable" as the rest of society and exercised their "natural selection" to exterminate them. Abortion supporters do the same thing today, babies are "inconvenient" and some of them may have gestational diseases so it warrants "natural selection" to "terminate them" because they are the weak and defenseless in society. The law of the jungle, the "me" law that says if I want it, I can do anything I want to get it and no artificial moral construction is going to stop me!
... it's nothing more than an attempt to discredit a scientific theory by demonstrating that it can be misused for terrible ends. This argument from adverse consequences is a fallacy and can be compared to an attempt to discredit Christianity by pointing to the Inquisition.
Curiously, though, it also confuses "natural selection" with the Nazis' planned extermination program. Rationally, this should is an example of intelligent design, although I hate, even as an in this example, applying the term "intelligent," to the Holocaust. It was done by design, though. "Malevolent Design" would be more like it. The above abortion argument is more of the same.
