Shooting a gun vs using "household chemicals and gasoline" to attack someone, to say nothing of knives or bare hands, are so apart from each other that I know for a fact that you have no experience with violence or how much easier it is to do violence with a gun vs other methods. You are just parroting teenager-level philosophy.
Besides all that, we have huge amounts of data over more than 100 years. Turns out, and this will shock you, when you have more guns you are more likely to shoot people and kill overall.
I don't want people to die because Bubba finds it badass to own an AR-15 they will never use except maybe to kill themselves or a family member (statistically, these are the no1 and no2 most likely people an American is to kill with their gun). Do as you will I guess but almost nobody needs to own a gun privately.
