I am atheist and while I am pro-nuclear power, pro-vaccine,and believe in global warming I am very much against GMO foods. I against them though because if the transfer of power they represent, not about the food itself. No study has ever shown GMO corn is any less or more healthy than natural corn. GMO foods shift power from the people and the farmer to the chemical company. GMO crops encourage the indiscriminate use of herbicides that put other crops and the soil itself at risk. If you don't believe this, try to grow a non-"Roundup Ready" (TM) crop in a field that has been sprayed with massive quantities of glyphosate for years.
This is a classic power play.
1. Sell seed that make it easier to grow a crop
2. Sell a chemical that removes the competition in turn raising yields
3. Said chemical poisons the soil making it impossible to grow anything but said seed
4. Profit...lots of it, for now and the future
