Also, there is another part of this debate that is often not mentioned: even for those people who don't have an issue with GM per se, there's still another reason to avoid them. In situations where the food is GM for RoundUp resistance (or any other herbicide) then those crops wind up getting heavily sprayed with those weedkillers, which then make their way into the food chain. So, if I want to avoid foods that are heavily sprayed with weedkillers, I would avoid GM foods (and/or buy organic, although that is pricier). To me, that's a really big issue, since many of the GM foods are made for herbicide resistance (as opposed to something like drought tolerance or extra vitamin A, where the crop isn't going to get deliberately sprayed with something harmful).
