We have seen over and over again chemicals which are "safe to consume" or "not that bad" actually do have very severe effects. It's just very hard to link cause and effect. When someone dies of cancer we can't pinpoint it to coming from the pesticide on the blueberries they ate a few months ago.

We have all these terrible illnesses that we ascribe to bad luck, and then all of these new chemicals we haven't fully studied yet being sprayed on everything.

Even things we know for certain aren't "safe to consume" are harmless at small enough doses. If I drink chlorine at 1000 PPM it's going to kill me, but drinking it at 1 PPM (roughly the amount added to drinking water in many places, and well below the level in swimming pools) is considered harmless to humans and kills pathogens, so it's a net positive. It's possible that chlorine at 1 PPM causes cancer, but that's a claim that would require evidence.

The same argument applies to pesticide or any other substance. Without talking about specific numbers, it's just speculation.
