Obesity is a "grave personal failing", you say. I suppose it is, just like poverty is. After all, we've seen those ads for those get-rich-quick programs. In fact, several of them post advertisements here on Town Hall! So if you're too dumb to answer these ads and "make $10,000 a week", that's your fault.
In the same way, we've seen the ads for those little pills, exercise machines, etc. which guarantee users they'll be svelte in just a few weeks. If you don't answer those, that's also your fault. After all, they're guaranteed to work, right?
Anybody want to buy a bridge?
