I don't trust the NRA and I'm a proud gun owner.
I think they're more of a voice for the gun manufacturers, suppliers, ect. but hide under the guise of the voice for the American gun rights advocate. I think their drop in lobbying power/membership over the years paints that picture.
Sure they've done some good, but they've also gone silent and disappear when major violent crimes happen in this country. The Sandy Hook shooting comes to mind. I can't support any group that tries to weaken background checks already in the books. I think most Americans would agree that background checks are a good thing.
