I'm a lib, and a progressive, and I support environmental causes....and the science is IN on GMOs. Pretty much every major science institution and university in the western world says GMO foods are no more dangerous than non-GMO foods. 
Science consensus: "GMOs are OK" ...Still, Monsanto's reputation is deplorable... they need to clean up their act.
