Obesity is a choice.
Obamacare is a violation of the 10th amendment. (That is in the Constitution, by the way, “yahoo!”, the same document that gives you the freedom to publish this pile of crap)
Obamacare is the danger, not obesity.
The greater irony is that most cases of obesity (discounting, for instance, thyroid problems) are due to personal health-related choices: I choose to eat potato chips instead of getting off the computer and cooking a healthy meal, or instead of going outside for a walk. Obamacare makes the state your own “private” health supervisor/enforcer, thereby removing that choice. It would not surprise me at all to see Obamacare mandate certain target weights, body mass indices, etc, and punish those who can’t hack it.
