You made the original claim without evidence. It's up to you to provide that evidence. You're engaging in a classic crank move there. I'm just applying Hitchen's Razor: "what is asserted without evidence may be dismissed without evidence." I have pointed out that these specific chemicals look to be less toxic than the class in general, so just pointing to evidence about the class in general is not sufficient.
