The problem with GM isn't that we've been "modifying" them. As you say, we've been doing that since the dawn of civilization (probably earlier). The problem with GM is speed. Those thousands of years acted as a wonderful buffer to see what works, what doesn't. What creates healthier humans and what has the potential to wipe out whole villages with a single mutation. It also provided us with ample time to adjust our digestive tracks to the new types of food we were ingesting. Dogs didn't become poodles in a thousand years. They became work dogs and watch dogs first and many hundreds of such generations of selection of traits. And we've seen the detriments of speedy breeding already. Dogs with breathing problems, hip and other bone problems. Dogs that can barely lift their own heads, have glaucoma, diabetes and other preventable misery. The difference between those thousands of years of breeding dogs and today? A few decades of speed.
