I agree with what you are saying. As far as law goes I dont think there is any mention of needing to "use your hands or fists" to defend yourself. You can sit there and let someone beat you up but the moment the person rises the level of the assult to a point were you can die you can use lethal force.

Here are the head wounds zimmerman had from getting assulted.
The police report shows Martin at 6' - 160lbs. The same report shows Zimmerman at 5' 9". Reguardless of size and weight I believe Zimmerman is a moron. He should of stayed in the car. As far as right and wrong I believe Martin shouldnt have been slaming his head onto concrete. If I was scared for my life I would of got the guy down and looked for an escape route - and high tailed it out of there.
My vote is that Zimmerman didnt break any laws but he is a moron.
I look at it this way. If I have a CCW (conceal carry permit) and I decide to walk down the worste streets in Harlem I am indeed a moron. In the same sentance if someone assults me while doing so and is slaming my head into concrete I can within the law to defend myself with lethal force.
