Hi John,
There is a lot that can still be discovered by further research, of that there is no doubt.
GMO foods have been shown to be substantially equivalent to their conventional counterparts. See: http://nas-sites.org/ge-crops/category/report/
We've been eating GMO sweet potato for millennia w/o any apparent side effects. See: http://www.pnas.org/content/112/18/5844.abstract
As to RNA degradation in GMO foods, same as the conventional counterparts. See: http://www.sciencedirect.com/science/article/pii/S0273230013000469
Again, no one can conclude that anything is 100% safe. I agree with you that there are varying interpretations on what constitutes safe. Our current regulatory framework has acknowledged that GMO foods are acceptably safe. May I suggest you spend your time trying to change that framework via legislation rather than commenting on Civil Beat if that is your desire. If you haven't you can go tour the Monsanto farm yourself. All the people I met were very nice, zero evil!
