Maybe after you make every neighborhood not only safe for children to play outside but make sure they have a place to play. And after everyone has a salary where they can afford fresh fruits and veggies instead of processed food. Some neighborhoods don't even have grocery stores in them. And after every school dostrict has a budget where every grade has a PE class and recess for free play. Maybe then we can visit that as a possibilty.
As Gator Blu indicated, it's not simply about what a child eats, it's also about what's available.
On the other hand if you eat too many calories daily, it doesn't matter if it's in the form of milk shakes or peaches.
So I wouldn't raise it to the level of "child abuse" but I do consider it to be somewhat "abusive."
And I'm not just playing semantics, I think there is a real distinction between those two labels.
