SodaDudeI don't know why "GMO" is a bad thing. Farming by its very nature involves humans engineering crops to suit their needs.
The difference between seed selection, cross breeding, and GMO is that with the first two, our bodies are still getting things that exist in nature. With the last, we are taking chances, without knowing what the long-term effects may be. Now, for the most part, they're almost certainly safe. However, that reminds me of the sign I put on my door every Halloween: "Ring doorbell for candy. We almost never eat trick-or-treaters!"
Look at, for example, high-fructose corn syrup. Two natural ingredients, fused together. But it turns out that, at least so far in animal experiments, the body doesn't quite know what to do with it; for example, in rats, the pancreas say, "This is sugar alright!" and secrete insulin, but the cells say, "This ain't sugar!" and reject the insulin.
