I never understood how someone could be afraid of one specific type of animal, be it spider, snake, lemming, whatever.
To those afraid of snakes: are you also afraid of skinks? legless lizards? eels? Where is the line drawn? I mean, I would be terrified if confronted face to face with something like a great white shark, and I have been within inches of rattlesnakes, water moccasins, sharks, barracudas, and more, but just categorically fearing a grouping of animals makes no sense to me, I guess
And as for black racers, they are non-venomous and eat rodents, so whats so scary about that?
I bet you're afraid of something and it's probably something others would think makes no sense.
