The liability insurance for damage to other than the insured vehicle is the issue here and it would, in my experience, be a rare case that that could be found to be that of the car's owner or actions of a thief.
I think you better check more carefully on what is/isn't actually covered; the OP's damages to his property would, I'm virtually certain, _not_ be covered by your insurance if it had been your car that had been stolen.
Think of it in this manner--you would not personally feel you have any culpability in the car hitting his fence would you? You weren't the driver, didn't cause the damage and (presuming) had left it secured properly (not w/ keys in, running in the driveway to warm up before heading out kind of thing), the fault/blame is all upon the thief.
When a vehicle is stolen, the injured party should seek damages against the thief through the thief's insurance or in court since it was the thief's negligence that caused the accident. As OP, says, "sometimes life just don't seem fair"...but it isn't all that fair to the car owner that without negligence he be punished, either...
