You can't help feeling the wool is being pulled over your eyes when the same companies that receive patents for their products, which according to the patent office must be "man-made", argue that genetic engineering is as natural as traditional breeding.

It's a good argument. If it's not natural enough to patent, it should be notable.

No good scientist could honestly say that GMO foods are the same as breeds. The process of adding genes is too uncontrolled. Also, many characteristics of GMO foods can't be established by breeding. They evolved in other organisms that benefit from the traits. To top that off, we still don't know what we are adding or disrupting when we are adding these genes. For example, the first Roundup Ready crop was established in 1996. We didn't even know about the functions of microRNAs at that time. Roundup Ready crops probably have different microRNA profiles, not just protein encoding gene profiles. There's too many unknowns to be able to call these crops the same as natural.

I've thought for some time that the best way to change this is the religious route. Kosher food is labelled. If you had a religious belief that prevented you from eating GMO, then you could sue the FDA. I don't think it's much of a stretch either. If you had to, you could found a religion. However, some existing believers might be persuaded. GMO does have a 'playing God' feel to it.
