Whose interpretation? IOW, you wouldn't be pissed off if the state in which you reside banned firearms?
I would. They'd have a hard time of it though. To start with it would require amending our state constitution. I believe CA is the only state that doesn't explicitly acknowlege their citizen's right to keep and bear arms in their state constitution, and IMHO, admitting them into the union without that was a mistake.
By the same token, the federal government can ban firearms if they can get an amendment ratified to grant them to authority to do that. I don't like the idea, and there could well be another civil war over it if they tried, but that's how it works.
