I never suggested shame as an effective treatment. But refusing to acknowledge the reality of the situation is not an effective way to discuss the problem. Obesity is the result of lifestyle choices, and those choices do impose their costs on everybody in society. Which is why I would be very happy (and I would suggest everybody should be happy) if an effective way to address the problem was discovered.

The fact that an obese person is harming other people as well as themselves might be an uncomfortable truth for them to hear. But ignoring it doesn’t make it go away.
