Believe it or not, I actually did find your joke quite funny, actually. Because female spiders eat the males, hence where black widows get their name. I don't know how you couldn't have figured that one out.
Snakes ARE lower than humans.
Well, maybe not an anaconda that's eaten a baby hippo and if I was laying beside it....
Why exactly are snakes lower than humans to be exact? What exactly did they do? Unless you are actually following religion, I don't see that lizards or snakes are anything more than animals. Doesn't really matter if an animal has fur or scales, you can still be friends with that animal. I have made friends with lizards and turtles before. I've even made friends with some of the insects, birds, and mice. I don't have a discriminating gene in animals, and believe all animals deserves a chance (although I wouldn't go near a predator that would eat me unless I was in a safe place, that is just being an idiot).
