I am convinced that part of the anti-GMO beliefs center on some ridiculous "natural genetic selection is inherently better than man-made genetic selection." Well, the evidence doesn't support that nonsense, but that rarely matters to those who rely upon their misinformed opinion rather than scientific evidence.
One of the tropes that have been passed around is about honey and high fructose corn syrup (HFCS) – honey is good, HFCS is bad. Scientifically, this is ridiculous, but the honey industry, disregarding the potential that science may actually refute that trope, funded a real scientific study about honey and high fructose corn syrup – well, let's just say that the results confirm that honey is not the "nectar of the gods."
