There are a lot of beneficial things that can do quite a bit of harm. Chlorine can be a disinfectant or it can be a poison gas cloud that can cause asphyxiation.

No one is suggesting spooning with a rattler... Well I once helped with a documentary on snake handlers, but that was a whole other ball of wax... Some people are just saying that the rattlesnake's role (or any snake for that matter) in the ecosystem should be respected... Or that's what I'm saying... Right now.
