Gestures, in love, are incomparably more attractive, effective and valuable than words.
~ Francois Rabelais
At the very least it's extreme negligence. How are stupid kids going to know anything about proper nutrition? It's up to the parents to see to their children's nutritional needs and fitness.
There are countless examples where lack of proper supervision can get a parent accused of abuse, why does nutrition get a pass? It's not just that little tubby is going to get picked on in school anymore. Now the prize for obesity is heart disease and childhood diabetes (yes, they had to come up with a name for it). Parents who are complicit in this are killing their children before they can even have a chance to lead a full and satisfying life.
"We’re going to close the unproductive tax loopholes that allow some of the truly wealthy to avoid paying their fair share. In theory, some of those loopholes were understandable, but in practice they sometimes made it possible for millionaires to pay nothing, while a bus driver was paying ten percent of his salary, and that’s crazy." -Reagan
