Until the average human is walking around looking like
this, there's not much worth panicking over. Most things you eat will have some connection to GMOs, directly or not. (Eat meat? If it's not fish, chances are it was grown on feed that was modified.)
Prop 37 in California (mandatory labeling of anything with GMOs in it, among other things) is only worrisome to me because of the precedent that you can hold a store owner accountable for the failures of the manufacturers, and because it will make food prices go up in the long run even more than they are already due to the need to design new labels and figure out how companies want to handle the fact that this requirement would only apply in California.
Cost is precisely the reason I don't buy into the whole "omg organic is so much better for you and won't, like, give you THE CANCER" thing. Who gives a damn if it's "better" for me if I can't afford to pay the extra costs - what essentially amounts to a luxury tax (or, more accurately, given the attitudes of many organics proponents, a "snob tax")? If I can't afford it, I won't be using it for very long - and as a result, I'm back to square one. (Please note that I
do agree with the position that the consumer has the right to know what is in the product they are buying - I disagree with the likely result of further increasing food prices and the additional requirements on people who shouldn't be held responsible.)
The politics and scare tactics used by both sides are shameful and just make me think of the whole nonsense with bird flu and SARS. Neither of those was actually a problem if you didn't act like a complete idiot and washed your hands regularly and covered your mouth and nose when coughing/sneezing, despite all of the the-sky-is-falling tripe running around.
I'd rather know I'm not biting into a fruit or veggie that's full of worms and shit, than fuss over some tiny risk of getting OMG THE CANCER 50 years down the road.
