Its ignorant for people to use fear as their basis for judgement on any topic.
As far as all pets go, should we kill pit bulls and rottweilers as they tend to be more aggressive (or so they are portrayed by television and movies), yet save everyones blue heelers because they are less likely to cause as much damage?
If you understand something entirely and know how it works, you have no reason to be scared of it. You can learn to respect the danger of a venomous snake and do what you can to avoid them. After all technically WE are the invasive species. Not them.
I personally know a half dozen people who have been bitten by the rattlesnakes here in New Mexico, and NONE have died. All were forced to seek immediate medical attention, but none died. And all of them were bitten because they were either stupid and messing with the snake, or because they accidentally stepped on it. Not the snakes fault, just its problem. And it took care of its problem the only way it knew how and used what it is equipped with.
