Is GMO/GE food actually harmful or "bad"? What about treated foods?

Here is the oft-cited corn pesticide decrease:

@Ruken

Incidentally, the use of genetic modification has massively reduced the amount of pesticides used on some crops. For corn, it’s down from ~200 g/ha in 1996 to ~10 g/ha in 2010. And yields have gone up, so the amount used per bushel has gone down even more.
