Have you heard of the FDA "revolving door"? How can you trust a regulatory agency that is ran by ex-executives of the industry they regulate?
I did grow up on farm so thank you for the credit. But please don't try to confuse cross pollination with gene insertion across different species. The first generates very small changes over a long period of time giving the ecosystem a chance to adapt. The second creates abrupt changes, which organisms may or may not be able to process correctly. Also nature doesn't use antibiotic markers to merge genes.
Can science go too far? Yeah. Maybe. But it hasn't.
I would argue that the atomic bomb is an example of science going too far. However, we are discussing GMOs here not science in general. To have a precautionary approach about new technology is not to be anti-science, like you're trying to paint it, is to be responsible.
Back specifically to GMOs, I have posted before on the subject. This pretty much sums up my stance.
