I encountered an anti-GMO troll at a recent meeting who started off his line of argumentative questioning with, "Lifespans are declining and we are seeing all kinds of new diseases and the U.S. is doing worse health-wise than the other developed countries, and many scientists think it is because of GMOs." That's the level of the rhetoric.
This fellow, however, had picked the wrong meeting for this kind of thing, because everyone in the room knew that every one of his premises was flatly false. If we had had stocks and a fool's cap, he'd probably still be chained up for display. But this kind of thing gets traction in the current media environment.
You’re right, Monsanto is more of a Mafia type organization with the best political and legal protection money can buy.
