“And by his teaching that it’s a natural force that’s far too complicated to be truly controled by man he prohibits the implementation of eugenics.”
Where does Darwin say this statement you made? Again, whether or not Darwin promoted eugenics himself is irrelevant. Eugenics can be a logical argument from the ideas he set in motion.
Now, don’t get me wrong, I’m not saying that naturalistic evolutionists are all in favor of eugenics, I was just listing their commonly held belief that all that exists came about by a mindless natural process that had no guidance other than mechanical forces that just happen to exit (for no apparant reason).
When you say that the world we have now is the result of “a truly amazing process” you’re just using flowery language to say the same thing naturalistic evolutionists say. You said yourself that the process makes “no direct statments regarding any designer”, in fact, that scientific inquiry is “unconcerned” with “prime motivators” but only with mechanics.
Don’t you see how Darwin’s ideas are just a short step to naturalistic evolution - not only does the process make no statement about a designer, the process is the designer - there is no God. The idea of God is pointless. You said that humans are “greater than the other animals because we developed a level of self awareness and situational curiosity not replicated by any other species.” Why does this make us greater? And, haven’t you just admitted that we are just a higher level of animal?
I’m not arguing that I am in favor of that, I’m just trying to get you to see how Darwin’s ideas can lead logically to a place Darwin may not have wanted to go, or you, or me, but to others, who are not restricted by any moral compunctions (because if there is no “designer” - no god, moral absolutes do not exist), may proceed to eugenics form these ideas quite nicely.
And yes it IS relevant. Because it's demonstrated over and over in history that long before Darwin was even a glimmer in his parents eye people have practiced various forms of eugenics. If you're going to hang it on Darwin you have to show how his theory of evolution was different than the Spartans obsession with physical prowess and all of the other forms of eugenics that have existed for the entire length of recorded human history. Eugenics is NOT a logical progression from evolution, it commits a logical fallacy in deciding to attempt to steer a natural process we don't actually understand.
The problem you’re having is that you're trying to assign morality to a scientific theory. Scientific theories aren't about morality, their about understanding what happens. There's no morality in the theory of gravity, there's no morality in the thermodynamic laws, they're just attempts to describe how things work. And there never has been, nor ever will be, room for crediting God in scientific theories. God is, scientifically speaking, a fuzzy concept without definable aspects or actions, scientific theories are about definable things with definable aspects doing definable things.
Your definition of naturalistic evolution is simply NOT how the reasonable people that believe in evolution think. It's just not there. Darwin himself objected to the people who tried to use his theory that way. It makes no more sense than how Medieval Europe treated the Jews based largely on the money lenders incident in the Gnostic Gospels, it's a gross misinterpretation based on a need by one group to define themselves as better than another.
The chain you're showing isn't logical. Its a build up of logical fallacies, one that many wrong headed people have used, but their logic sucks. They take what Darwin said add some demagogy fallacious definitions and cognitive bias (among other things) and arrive at a conclusion that anybody that's taken an introductory course in philosophical logic would scoff at. By saying their beliefs follow logically from anything you're giving these scumsuckers and racists (which is really what eugenicists are) and undeserved legitimacy.
