I don't really think it's a valid comparison. There's no such thing as "second-hand high cholesterol." Thunder thighs aren't contagious, nor do they spread air-born carcinogens. What one lard-ass is eating as no effect on your health or mine.

That being said, though, I too am no huge fan of the "holier than thou" stance that some non-smokers take. A non-smoker who takes it upon themselves to sit in a designated smoking area, only to piss and moan because their's smoke in their face...well they deserve to be punched in the throat.
