Several things. First, plants do not have to be altered with animal or bacterial DNA in order to be called GMO. For example, if I studied drought resistance in plants and was able to identify 3 genes in millet that make it so exceptionally drought tolerant, I could theoretically integrate those genes into the genome of corn and make corn exceptionally drought tolerant. This would be a GMO crop, but almost certainly would be a good thing. So the scare tactics about GMOs are meant to bypass reason, and ignite hysteria.
Second, we have been genetically modifying organisms for thousands of years, by selecting the most fit crops or livestock and mating. Creating new, stronger breads of horses, for example, or increasing yields on corn. This is the high tech version. And yes, there are drawbacks at times, round-up resistant weeds are a fine example. However, the issue you listed is with the new herbicides being used, not the GMO crop itself.
Third, always, always, always cite the study you are referring to.
Fourth, a real world example of a GMO fish, where the only thing done was to alter Atlantic salmon with a gene that helps production of a growth hormone in Chinook Salmon, in order to decrease time to market:

Those are all good points to keep in mind Junior, but as mabrown pointed out genetically modified can also mean splicing genes from other plants and animals. That's were the biggest concern is with GMOs. There just isn't enough research out there right now to make any kind of conclusion about the safety risk of eating those types of foods. However there are some personal accounts from people having reactions to food they have no business being allergic to only to find out it was some kind of GMO.
