How about this: Treat the amendments like their authors did.
For guns, take away the right from anyone you don't feel is worthy of it (like the Founding Fathers did) - AND, for the select people you deem worthy of it, it's not a right, it's a DUTY. And you demand that they buy a firearm that the state approves, and then require them to go to regular training camps at their own expense.
I foresee a quick end to the gun debate following that.
