Yea, how is this bad? I'm not saying GMOs are inherently bad, but what's wrong with giving people information? Is there something tangible we can compare this to?
It's sort of like nutrition labels. There comes a point at which there are diminishing returns in including more information. Even there, government action is more intended to provide a standardized format for the info some consumers desire so as to make it easy to locate. In the absence of any demonstrated harm to people from eating GMO products, requiring products that contain them to note that seems like overkill, especially since producers are free to trumpet the fact their product is GMO-free if they want so there already is a
de facto labeling of GMO products going on. The situation is similar to BGH in dairy products, or more generally with organic foods.
