Everyone is so quick to slot you onto one side of the culture war that ambiguity actually arouses fear in some members of the audience if your intentions aren't laid out clearly, since they can't easily determine which "side" you are on. A disturbingly large number of people, I think, really do have such a mindset.
I think the synthesis you've identified is correct, because even if you do decide to deal with something ambiguous it is expected that you tip your hand clearly to the audience as to what you feel the "right answer" is. People consume entertainment the way they consume fast food -- an easy burst of pleasure that lightens the burdens of the day for a brief moment. To be confronted with indeterminacy or obscurity is like finding a hair in your burger.
