Just read this (A Moderate NRA - The Dish | By Andrew Sullivan - The Daily Beast) and was reminded that my early years with the NRA (yes, I was a Junior Member) were all about hunting, and hunter's safety. As this post suggests, an NRA devoted to that would be more moderate on a lot of environmental issues even if they were still pretty conservative on access to guns.
But they aren't. I get the sense that the NRA is really only about defending the right to own guns that are about killing people.
And that is a shame.
