How was it different? Well, his argument went like this: you need a car but you don’t need a gun. Essentially, that’s the whole liberal gun grabber argument. You don’t need a gun therefore any restriction is justifiable considering the adverse impact firearms have on society. (not my argument, the gun grabbers).
I have never needed a fire extinguisher either, but one is sitting in my kitchen just in case I ever do. If he ever has someone at his front door trying to break in with the cops twenty minutes away if it's a slow night, he'd realize how much he needs one too. I doubt if you can ever convince someone so profoundly afraid of inanimate objects of that, however.
