When your corporate response is right out of the big tobacco 101 playbook then something is wrong. No labeling allowed, industry funded "studies", where have we seen this before?
There have been plenty of studies showing health improvements for people off of GMOs.
The Tobacco industries past, isn't evidence of GMO's being unsafe. That's basing your ideas in fear and a lack of trust. As far as the labeling thing goes, if there's no proof that it's unhealthy then forcing companies to label it as such, really isn't fair to those companies, and buys into the fear mongering.
Plus the free market works. There is a market for non-gmo foods and organic, and those companies are more than happy to voluntarily label their products to get your dollars. Do we really need a law to label non organic produce, when organic produce is already labeled?
