Neurotoxin for insects = terrible evidence of toxicity in humans. We go by evidence of toxicity in humans, and all evidence shows it isn't toxic in the doses people consume it. If you want to say we haven't discovered the secret terrible cancer causing agent in coffee yet, but just you wait... Well it's going to take a lot of evidence. There are lots of controlled studies saying it's pretty good for you. I think what you're picking up on is a distrust by analogy. In the past we thought some things were safe, but they weren't (smoking etc). But the opposite of being ignorant about the effects of chemicals we ingest isn't to suddenly say everything is unsafe. It's to test everything. And we have tested caffeine, and it's safe.
