Personally, I trust genetically-modified organisms more than I trust non-GMO's that are treated some other way before they make it to my dinner table. Would I rather have a potato genetically-modified to resist blight or one that came from a plant sprayed with fungicide? Would I rather eat a chicken modified to be larger or would I like a regular chicken pumped full of saline (to get the weight up for sale)? Would I rather drink milk from a GMO cow or just have the hormones added to the milk after the fact? Messing with stuff at the genetic level has been going on as long as we have been domesticating crops and animals. We favor certain traits and cull others. This is just the next step in that phase. The real harm, I feel, is with all the additives that come during the food production that have nothing to do with genetics.
