Are you saying that genetically modified food products are exactly the same as non genetically modified food products?
No. I am, however, saying that GE crops are no more different than those derived from hybridization, mutagenesis, bud sports, somaclonal variation, induced polyploidy, ect. all of which you eat unlabeled all the time, and you probably don't even know about them. I'm saying that unless there is a difference to the end consumer which is significantly different than what could otherwise be expected from the crop, then it should not matter for the purpose of labeling.
Why are you irrationally singling out one aspect of crop improvement, one that just so happens to be controversial (but not scientifically controversial [and yes, as a plant scientists, this stuff is about as controversial in my field as vaccines or the validity of evolution]), without demanding anything else be labeled (like other aspects of crop improvement and production, including but not limited to the other crop improvement techniques I mentioned, rootstock, PGR use, biocide use, fertilizer use [where's my poo label on organic foods?] date and location of harvest, ect) , without telling the details (such as gene inserted or what it does, ex NPTII, Bt, EPSPS, bar, CSPb, various cp genes, ect), without telling the benefits (ex. reduction in mycotoxins, reduction in insecticides, shift away from harsher herbicides such as atrazine, saving crops from viral infection, ect.).
You seem to want to be very specific and selective in what you tell the consumer, which is very fishy when we are talking about a thing that can be identified simply by knowing what you are looking for (corn, soybean, canola, cotton, alfalfa, sugar beet, summer squash, and papaya are all the GE crops out there). I can always tell if something I'm eating is likely to contain GE ingredients; why can't you educate yourself enough to do the same? Millions of vegans, Jews, Muslims, and Hindus with religious or personal dietary restrictions do the same, and they don't deserve a special law catering to their beliefs. You don't either.
If so, how can they be patented?
The same way non-GE crop varieties such as Clearfield wheat, Beneforté broccoli, and Snowsweet apples can be patented. You do realize that non-GE crops can also be patented, yeah? My question is why you're trying to use a legal argument on a topic that should be decided on the scientific basis of the things; if they are scientifically different, th
