As with most science, their are deniers that take bits and pieces to put together "evidence" against the massive and persuasive evidence that convinces most in the field. Even some doctors are quacks, or like doctor Oz, are entertainers. Science is not a democratic enterprise, one scientist with well designed experiments can disprove the "establishment", but extraordinary claims require extraordinary evidence. GM crops are safe, evolution is real, global climate change is happening, Flu shots do much more good than harm (but this year only work in 2 of 3 cases which is not unexpected for a vaccine against multiple viruses), and efficient cold fusion has not been accomplished. If you think there is a conspiracy by scientists to deceive, you can believe that, but believing does not make things so, no no no, no no no...
