Any gun owner who isn't--needs to be. The gun-grabbers will never quit (and in fact are gearing up for a new round of propaganda to stimulate more gun laws---see all the article here about Bloomberg's meeting with other "big-city mayors"--although probably better to call them "BLUE-city mayors).
Every Freeper should be an NRA member and put the initials in the tagline.
There's no excuse for a paltry 4 million members out of 80 million gun owners.
