We aren't criticizing this craigslist post for providing disinformation, but rather the negative associations it perpetuates about snakes and snake owners. We all know that dogs kill far more people yearly than snakes, and that any large breed dog could seriously injur a child at any moment, but we don't automatically associate a golden retriever with a dead kid. The sad fact is that a large percentage of the population, regardless of hard data, associate snakes with bodily injury. CL posts like this only further these false associations in the minds of illogical people. We have learned throughout history that human populations are usually awful at making decisions based on logic and data. It's the same deal with gun laws. Knives hurt many more people than guns yearly, but you don't have to jump through hoops to buy a paring knife.
Point is: Don't feed the hysteria promoting propaganda machine.
