First, GMO's are not inherently dangerous, messed with in a lab, transparently, and improved upon at a fast pace (technological innovation). The same would be true of big pharma if the emphasis was truly on acquiring more knowledge than profit. What makes any technology dangerous is shortcuts for profit, which becomes even more prominent when you start trying to push an industry to the shadows through demonization. The same is true, in the case of big pharma, when the public adoption an industry (pills to solve problems) without a focus on technological innovation/understanding instead. If cloning, stem cell research, nanotechnology, etc was given public adoption as much as "curing cancer", "fighting aids", and other futile endeavors were the world would be very different by now.
To try and stop the future is the most primitive and savage thing you can do. Grain-based farming was a horrible futuristic trend that gave way to standing armies, vastly spread civilization and expanded population at the cost of lower overall health, until today when it's finally possible to get high quality foods, directly because of that grain-based farming "technology" which paved the way. GMO's have the potential to be super foods which are better than any natural counterpart, it's all about how good the technology becomes, not what state it's in right now.
The defeatist attitude is demonizing anything that challenges the norm, when one should strive for more understanding/testing/control instead. I agree that letting loose a poorly understood technology (GMO's) into the food supply is a bad idea at the current time, disagree that GMO deserves the label "very dangerous", drowning is "very dangerous" but people don't talk about it with an exaggerated panic whenever a bottle of water is around, because it's not demonized. Unfortunately, the public at large is a mob that is easily manipulated when there is a financial incentive, and there is one here, so the futile resistance method of the few to reject GMO's is only going to delay the progress that makes GMO's a useful technology in the end, instead there should be a push for control and understanding which an industry can actually respond to and grow with, it can still operate within those requirements. Telling it to just cease all activity for their new holy grail is only going to be met with shadowy corruption.
