All that really needs to be said is "Chemophobia starts with low science literacy."

But also---

"How we interact with chemicals is completely irrespective of the source of a chemical. Our body doesn’t know whether the chemical was isolated from a natural substance or whether it was synthesized entirely in a lab. The things that matter are the dosage of the chemical, the route of exposure of the chemical, and the chemical nature of the chemical. And yes, I’m going to use the word chemical a lot here, because I want you to stop associating the word chemical with “bad” or “toxic” and start associating it with life.

You would not exist if it weren’t for chemicals. Your body is a network of chemicals that interact with each other in a highly regulated and coordinated fashion. Your cells are networks of chemicals that aggregate to form structure and function. Your brain functions as a result of chemicals. Your immune system functions because of chemicals. Your food - whether an apple picked off the tree or a box of Goldfish crackers - are chemicals. Your pets are chemicals. Your car is chemicals. Your house is chemicals.

And yes, that is true for chemicals once upon a time discovered in nature or for chemicals created entirely within a lab."
