Truthfully, with the ways that Monsanto treats others, I think others don't consider the ways arguments are crafted in their favor by others who couldn't care less...and I'm reminded of the film "Thank You For Smoking" which went into a lot of depth on bringing the issue to light.
On a great example of rhetoric being used to manipulate the masses, the film begins on the set of a talk television show. On stage there's a panel of health professionals, a boy dying of cancer, and Nick Naylor (the spin doctor of tobacco companies). To support the argument that smoking is bad for our health, appeals to human emotions (pathos) are made by the tv show's hostess. And the audience is shown a young man who had a bright future but was diagnosed with cancer.
1,200 people a day are killed by smoking, narrates Nick Naylor (the hero of aspiring politicians and salesmen) - with Nick pointing out the logical argument- "We don't want Cancer boy dead, if anything we'd be losing a customer." Essentially, the man pulled an old trick and turns the argument on the Health Service guy, "He wants Robin (cancer boy) to die, so that they're budgets will go up. This is nothing less than trafficking in human misery, and you ought to be ashamed of yourself!" ..and later, Nick ends his rant with something everyone can agree on, but is completely irrelevant to the topic. "There's nothing more important than America's children."
