If you dislike my analogies, you'll probably really hate Lilek's latest:

Imagine if you woke from an operation and discovered that your tumor was gone. You’d think: I suppose that’s a good thing. But. You learned that the hospital might profit from the operation. You learned that the doctor who made the diagnosis had decided to ignore all the other doctors who believed the tumor could be discouraged if everyone protested the tumor in the strongest possible terms, and urged the tumor to relent. How would you feel? You’d be mad. You’d look up at the ceiling of your room and nurse your fury until you came to truly hate that butcher. And when he came by to see how you were doing, you’d have only one logical, sensible thing to say: YOU TOOK IT OUT FOR THE WRONG REASONS. PUT IT BACK!

You'd probably also be saying, "What are you going to do now, take out all the tumors?"
