You have the right to not be threatened or attack. How exactly is someone merely possessing a bomb a threat to you? The same logic applies to guns, knives, heavy objects. Shall we just cover the planet in foam padding for you? No, wait. You could choke on the padding. I guess nothing is safe.
I am treating you as an adult capable of reasoned discussion. There is no comparison between someone committing suicide with a gun and someone committing suicide with a nuclear weapon. One is a private tragedy and the other kills everyone for miles about. You know this; so why are you making arguments you don't believe yourself?
