Stem-cell research itself is science; whether stem-cell research is good or bad, or deserving of funding, is NOT a scientific question.
The study of global warming is science; whether global warming is a good or bad thing, or worth addressing through public policy, is NOT a scientific question.
The study of human sexuality & its biological components is science; whether there should be an abstinence-only emphasis in sex education, or some other option, is NOT a scientific question.
