The NRA has become a progressively more despicable organization for decades

It's not just that they want lunatics to be able to purchase assault weapons at will (and to be able to make them full automatic through buying the conversion parts at gun shows), but they want no restrictions on such purchases at all. They wouldn't consider the fairest compromise to insure the safety of the public.

The government wanted to have a way to track the fertilizer of the sort used in the truck bomb to demolish the Murrah federal building in Oklahoma City, so that it could not be diverted to be used in domestic terrorist attacks.

It would have been quite simple. The fertilizer that could be used for such a purpose just needed chemical "tagging" so it could be identified by the source if it was misused.

The NRA successfully opposed that legislation. 

What has that got to do with the "Second Amendment?"

How does it feel to be a charter member of the "world's oldest profession," Paul?
