But it's fine to put that same person under the knife for weight-loss surgery? I don't buy it. If I want to take the risk of general anesthesia (I've been fat all my life, and other than making me vomit, it's never harmed me, and I've had lots of surgeries), then I should be allowed to take that risk.

(Not to mention that no one agrees on what the definition of "obese" is, no one agrees on the actual risk, etc.)
