But more to the point, I don't see the benefit to many organic foods.
There is often more pesticide residue on organic foods than there is on non-organic, and some of those pesticides are QUITE TOXIC.

I would be more concerned about household chemicals (fumigation, bug sprays, etc) than I would about most foods. That doesn't go for some food grown or processed in India or China, which can be dangerously contaminated.
This Slate article contains some more realistic information:

Research conducted by Bruce Ames, director of the Nutrition & Metabolism Center at the Children’s Hospital Oakland Research Institute, has found that Americans consume about 1,500 milligrams of natural toxins from plants a day, which is approximately 16,000 times more than the 0.09 milligrams of synthetic pesticides we get from food every day. These natural toxins are for real, too: According to Ames’s work, the natural chemicals that are known to cause cancer in animals and are found in a single cup of coffee are about equal in weight to a year’s worth of our exposure to synthetic pesticide residues that are known to cause cancer. In a 1996 report, the National Research Council, a non-profit institution that provides expert advice to the government, noted that “natural components of the diet may prove to be of greater concern than synthetic components with respect to cancer risk,” in part because “synthetic chemicals are highly regulated while natural chemicals are not.”
Plants have had millions of years to evolve chemical warfare on their own, and they're good at it. We also evolved eating the products of that war, and we are adapted to it.
