It is because the industry has done a great job as labeling the critics as anti-science. Yet the source of the controversy for anyone who spends enough time to look into it is other scientist.

It is somewhat ironic, that most everyone agrees the GMO companies are quite evil in nature when it comes to their business practices. Yet the same people say we should absolutely trust the same companies when they make claims about their products benefits or safety.

I think part of this is because progressive science fans see the potential of GMOs and latch on to the possibilities and ignore that we are still quite immature with our understanding and implementation of the technology.
