The left and GMOs

From the Washington Monthly (Liberals and the Science of GMOs):

...There is near-universal consensus among the world’s scientists that man-made pollutants are trapping heat in the atmosphere and wreaking havoc on the environment. Yet when pollsters ask voters whether they believe temperatures are climbing because of human activities, most Democrats say yes and most Republicans say no.

Democrats may wag their fingers contemptuously at this, but the pot would be calling the kettle black, because many of them are just as stubbornly skeptical on the issue of genetically improved foods, even though the scientific consensus about their virtues is no less universal. That consensus was further cemented last month by an all-star committee of the National Academies of Sciences, Engineering, and Medicine, which issued a 400-page report concluding that genetically modified (GM) crops are safe to eat and do not harm the environment. 

Either way, such denials of scientific consensus read like newly discovered scenes from a 17th century play. Why is this still happening?...
