I agree that the idea of Frankenfood is hysteria. My fear of GMO's is due to my distrust of Monsanto, their near monopoly position in the global food supply, the legal tactics they use to bankrupt farmers for having the unmitigated gall to unwittingly use Monsanto seeds that blew onto their farm, and their regulatory capture of the FDA. There is a revolving door of former politicians they employ.
It's also unconscionable how they're able to ram through legislation that removes labeling of foods that are GMO's. Even if someone has an irrational fear of GMO's, they should still have the right to know the origin of their foods. Logic clearly dictates that the rights of the many outweigh the avarice of the few. God forbid they should try to educate the public on their safety or be open and transparent about their products.
