What really gets me is the false dichotomy between organic and conventional. It reminds me of how medical quacks try to differentiate between conventional and alternative (or naturopathic or whatever) medicine when the rational thing to do is to focus on what works, not what it is called. Some organic techniques are good. A lot of biological techniques like intercropping, crop rotation, focus on soil microbes, insect mating disruption, passive pest control methods like use of predator insects, increased use of biodiversity, ect. are positives. But that does not mean you should be dogmatic about it, which is exactly what organic is: naturalistic dogma. A natural pesticides is fine in organic production (and before anyone assumes organic uses no pesticides, look up the approved pesticide list), but not a synthetic one, simply on the basis of its origin? That is the classic appeal to nature fallacy. And while it is true that excessive fertilizer use has many negative consequences, why should responsible use of synthetic fertilizers be forbidden? Soil fertility management is damned complex, and it is presumptive to think only 'natural' methods are going to be of sustainable benefit. Genetically engineered crops are a great example of the naturalistic nature of the organic dogma. You can apply Bt to a crop, but if the crop does it itself, it is suddenly forbidden? Even something as simple as an apple modified to not brown can never be organic. Why? It is not natural (or rather, it is not natural and is popularized, unlike things like mutagenesis and chemically induced polyploidy).
My point is that organic has some things going for it, but not because it has some special label like 'organic'. What it has going for it are the biological techniques it uses. Of course, these techniques are not exclusive to organic; if you think your average farmer does not pay attention to things that can make their operations better, you are mistaken and have probably never even set food on an actual farm before. Ultimately, the focus should be on the scientifically verified merit individual practices, not on some label that represents a collection of practices grouped together based on the appeal to nature fallacy with some after the fact justification. The dichotomy misses the point entirely (unless the goal is marketing of course, in which case oversimplifications work great, and absolutes tend to create more true believers than nuance). Even if organic did produce more nutritious food, that would still not support the superiority of organic so much as it would indicate that there is an attribute of some growing method causing the increased nutrition that should be determined, explained, and focused on.
