The fact of the matter was that anti-GMO folks use non-scientific scare tactics about health as their primary means of activism. And then, when confronted with empirical data that GMO's are just as safe as non-GMOs, they turn to the anti-corporation argument.
...sometimes it is not about the science and no amount of data can convince people.
That statement right there is very telling, and why I keep referring to the anti-GMO crowd as a cult.
My sister watched one documentary on Netflix and decided to become anti-GMO. I asked her if she watched anything telling the other side of the story. She goes, "This told both sides! It was a documentary!"
Of course, she's a JW cult member, so she's prone to being deceived, but still, that's why most vocal opponents of GMO's are anti-GMO. Because they read a couple sensational articles on Salon.com about them, or they watched one documentary on Netflix and then made up their minds based off of biased information.
