I'll be ashamed of the Dems for you Plane, though I'm honestly not really either party.
I've said that this is coming for a long time, as soon as society started going after tobacco companies. The next logical step was junk food, some states and municipalities are beginning efforts to try and tax junk food, much like a "sin" tax for tobacco or alcohol. Eventually the government is going to have to learn that people will do what they do regardless of health benefit. As with most sin taxes, a junk food tax mostly hits poor and low income folks.
Denying food to someone because they're fat is like denying a bank withdrawal to someone that is rich.
