I know we make enough food to feed anyone on the planet, but it doesn't mean throwing away food is morally acceptable.
Call it a taboo or whatever - I still remember when as I kid I was invited to a friend birthday and we ended the party by running a burger-thowing contest. It felt wrong then, and it still does now.
Even if we make far more food than we could possibly consume, food like water and oxygen is something special - something we humans require to exist. We can survive without shelter and medicines. We can't without food, something which certainly helped giving it a "special place" in our list of taboos.
Considering it as something just like any other good does not resonate with my values - even as a hacker who would otherwise consider that a non-issue if applied to say mice and keyboards.
We are the most spoiled 1% of the humanity and we act like we don't care - that might be acceptable depending on one's philosophy, but NOT for the crucial things mere survival depends upon.
Sorry, but it's just plain wrong.
