Reading your post 365, I see that you do understand what is being done to destroy natural agriculture in the courts, so why are you not an ardent supporter of prop 37?
All of the “farmer Bs” of North America are being systematically crushed with the assistance of the courts. They have insufficient wealth to play this billion dollar game, and thus have no recourse.
Because voluntary labeling efforts under private certification will be more effective and accountable. This kind of labeling will fail to deliver on its purpose because of corruption in the designation of GMO or not, the ubiquity of the labels, it will load farmers with the responsibility of documenting everything else risk being sued, fail to distinguish GMOs that are mere controlled hybridizations from serious and potentially dangerous modifications, and give the big producers abroad an advantage in the marketplace due to economies of scale in paperwork and their "come and get me" locations.
Prop 37 is the wrong answer to a legitimate problem. I think competing voluntary approaches to providing useful product information is the better way to go.
