Californians: What is wrong with Prop.7?

There is so much negative press surrounding this proposition. It seems everyone is opposed. I don’t get it. I’ve read the voter guide info, and I can’t see what ll the hub-bub is about; it sounds like a good idea to me. Can someone explain it to me in basic terms, with as little bias as possible. It’s one of the few props. that I am still unsure about.
