I'm not a tinfoil hat type who won't touch GMO because of any silly number of silly new age concerns or paranoid fantasies. But, that doesn't mean people don't have aright to know what they eat. Sure labeling won't solve problems like in TFA, but anything additional that informs consumers is a good thing. And knowing the potential pitfalls of different food choices should be a right. The current inability of shoppers in the US to know what foods are GMO means consumers have no choice. It also leads to suspicion and support to the luddite part of the anti-GMO crowd.
Labeling is the first step to educating the public on GMOs and what they provides as well as potential impacts worldwide from GMO such as increased yield (with less chemicals) on one hand, and things like genetic diversity concerns and the role of seed/pesticide suppliers and patents on the other. The reason labeling here is so opposed by the industry isn't because of some conspiracy or concern that customers will decide to stop eating their product, or radically change their diet. Americans have known what we eat and its volume are deadly and McDonalds hasn't been shut down.
Instead the reason behind non-labeling is to keep the status quo, labels on food mean questions, questions lead to competing information and the rise of the conspiracy theorist. Not having to label is just the path of least resistance. But keeping a few loud mouth idiots quiet isn't a good reason to not engage honestly with the public about a very profound change in the way we produce food, and quality to support a growing population.
