You are allowed guns but the reason that you have for owning a gun has to be a little bit more than “because I want one”.
Yeah, I don't like that and I don't even own a gun. I don't think governments should have a monopoly on violence or the tools of violence.
With the exception of nukes, but mostly because I don't think anyone should have those. If only governments have them though at least they have some level of self interest to not nuke their own population.
Then again I'm pretty nihilistic these days, maybe I'm ok with the McNuke now. As long as I'm instantly vaporized if one goes off, I don't want to experience the black rain and slow agonizing radiation death.
I also don't think its the government's business should I decide to buy a gun what I intend to do with it. Will I ever buy one? Probably not. But still, principle of the thing.
