Is this really the duty of politicians though? Certainly there's been a lot of discourse about this in the current landscape, especially from those attempting to impart their personal ethics and morals on the political landscape, but this shouldn't be the duty of the government, but the duty of individuals (chiefly parents) as well as that of a society as a whole. Government shouldn't have any business in what is ethical or moral but in what is legal (which is sometimes, but not always a reflection of ethics and morals).
"Enforcement" is the use of force to assert an ethical and moral position. "Legal Enforcement" is the monopolistic use of force to assert an ethical and moral position. It's not possible to enforce "what is legal" on others without asserting a morality.
Speaking of trust, I've been at the mercy of unscientific and irrational politicians my whole life whom I do not trust. I do not trust you because you are a "family man", or a "common man" or because you are "spiritual." In fact, if you are spiritual or religious, I trust you less by the fact that you subscribe to a non-rational philosophy.
Finally, I won't pretend to want to avoid stepping on toes. I'm sure the above will step on toes.
edit: and before someone accuses me of having no morals or ethics, I can assure you that I do. If I were forced to join an organisation, I suppose I'd have to join the secular humanists.
