It's pretty easy to educate yourself about venomous vs. nonvenomous snakes. All it takes is a little time and effort. Most people put far more effort into watching trash TV than they do learning about things in the real world, so I don't have much sympathy for anyone who says, "But what if you make a mistake?" It's not an easy mistake to make, you just have to do what hunters should do: observe, learn, analyze.
It's amazing how many people can identify every species of duck in the western hemisphere, can tell the difference between a '67 and a '68 Camaro and tell you every movie Clint Eastwood ever played in, but when it comes to something as important as being able to identify a venomous snake, they forget to pay their Google bill.
