Mark Bittman, writing for the New York Times:
Redefining the argument may help us find strategies that can actually bring about change. The turning point in the tobacco wars was when the question changed from the industry’s — “Do people have the right to smoke?” — to that of public health: “Do people have the right to breathe clean air?” Note that both questions are legitimate, but if you address the first (to which the answer is of course “yes”) without asking the second (to which the answer is of course also “yes”) you miss an opportunity to convert the answer from one that leads to greater industry profits to one that has literally cut smoking rates in half.
Great thought, but easier said than done.
