As someone who used to keep reptiles (and all sorts of other animals), I'd have a good laugh at them too. Most actually harmful snakes are easy to get to know the shape, patterns and habits of. There are a few wild types near where I live but they're hardly deadly. Unless you're a child or a dog, perhaps.
My male housemate isn't exactly hysterical when there's a spider in the place, but he won't tolerate sharing a room with one. I could care less unless it's trying to get on my face.
I think snakes and spiders tend to bring out freakout responses in both sexes in about the same ratio. My sister, who used to hang around with me, is unafraid of reps and bugs. Maybe it goes back to childhood experience or interest. People with no interest in these things tend to be more scared.
