Your general point I can't disagree with: Philosophical foundations and beliefs have far-reaching real world consequences. But you really go off the rails when you think that accepting the Theory of Evolution as valid & generally correct is somehow inherently responsible for the evils of the world.
The belief in the theories of the properties of electromagnetism has brought us death by electrocution. The belief in the germ theory of disease has brought mankind biological weapons. The theories of quantum mechanics has brought us the transistorized computer, which has enabled the delivery of atom bombs from space. Have these theories had any good effects, too? And more to the point: Do people who study & accept the truth of these theories assign any moral value to electrons, germ theory, or quantum mechanics? Or are well-supported theories merely tools, which can be used just as easily for good as for evil?
Seriously, why is this such a difficult question for some people?
BTW, that's why Islam and modern Iran are so frightening. If we know what they believe, we can figure out what they will DO.
I too am frightened by what these doctrinaire creationists would like to do. Not sure why you'd want to bring THEM up, though. :-)
