In all fairness, labeling it Genetically Modified would be scientifically accurate.
In all fairness, requiring them to be labeled as GMO would not be scientific all all.
The assumption that Genetic Modification is a horribly evil thing is certainly superstition, but I consider that a separate issue.
It is not a separate issue when people are trying to subvert the government regulatory process to promote their superstitions.
I'd actually like to know a whole lot more than that myself.
Just because you would like to know doesn't mean other people should be required to tell you. Far more people are concerned about whether their food is kosher or halal. Should we have government regulations requiring food to be labeled as "non-halal"? Of course not, because there is no nutritional difference. Butchers that prepare their meat using kosher or halal methods should be free to advertise them as such, but the government should stay out of it. Same with GMO.
