My problem with the anti-GMO folks and other movements similar to them is that they just don't grasp the big picture. When you're a one issue idealist, you operate with blinders on, regardless of whether you're left, right or other. I see this with Republicans who cling to the idea that they have to stop abortions and the notion that they're going to have their guns taken away. I see this on the left with those who think that by working with moderate Libertarians or Republicans on one issue, that they'll lose their high ground on others.
The recent "Monsanto Protection Act" hoopla has shown me just how prone to overreaction and fear-mongering people really are. We certainly should be concerned about foods that aren't natural and what they could do to us. I personally stick to a semi-Paleo diet, avoid processed foods and eat organic as much as possible. The problem is that when you subscribe to a particular religion, diet or ideology, you'll believe anything that comes along, and there's plenty of people who want to capitalize on that. For example, I'm gluten intolerant. I've gone searching across the internet for sources that can help me with that issue and there's been a number of them that have provided some useful information, and many more who want me to believe that by only buying their product, only then could I be safe.
When ideology meets an opportunity for profit, paranoia begins to resemble a runaway train. If we were to believe half the stuff that I run across in order to maintain my health, we'd never leave our houses, gyms, or health food stores. As the saying goes, "On a long enough time line, the survival rate for everyone drops to zero". What does that mean? It means that no matter how healthy you eat, how much you exercise, or whatever precautions you take, you're gonna die one day.
This isn't to say that we should get all nihilistic, start our days off with a bottle of whiskey and a pack of smokes with our coffee. We should be cautious, we should make good choices and avoid dangerous things. However, we shouldn't allow fear to dominate our lives and instead of blindly believing things that you see on the internet, do some research with a healthy dose of skepticism, and then make a decision on how you want to go forward.
