Absolutely correct
This is what creationists (and real scientists) should be most upset by: that evolutionists and scientists, are attempting to become moralists, to mix morality and ethics into their hypothesis and conclusions, areas in which they have NO BUSINESS.
I have yet to talk to a scientist, or a socalled "evolutionist" that claims that evolution can give you any sort of morality. It is a scientific theory, nothing more, and nothing less, if someone uses that theory for the basis of their morality, they are an idiot, science does not claim any type of morality, let alone a moral superiority of any type.
Morality is a philisophical, even a religious area, and science has no wanting, nor need to be the basis of anyones morality.
To say that someone bases their morality on the understanding of evolution is idiotic, if not moronic in the extreme.
Scientists are typically wiser than to make that leap, but there are millions of idiots out there being manipulated by politicians and causeheads who are using science as 'proof' of their worldview, implying that only worldviews based purely on science are valid.
Evolution, Global Warming, etc. are all cases where politicans and other 'causeheads' are using science as the basis from which to argue public policy. A leftist worldview is generally atheistic and relativist, so leftist politicians/causeheads hold up science as the highest marker or judge. Science becomes their god. The fallacy is that science is 'all we have' or 'all that we should use' to shape our public policy.
