If you hate the NRA, it's easy to paint this political stance as nothing but a move of pure-gun-lust...however, such stances set precedent for other privacy related rights. To put it another way, just because the ACLU defends pornographers, it doesn't mean the ACLU is doing it purely out of love for pornography.
edit: In any case, there will never be a "NRA for Privacy". Pause and think about it. What does the average person experience in terms of privacy invasion? Not too much, and not at a constant clip. Would that average person be able to discern between heavy privacy protections versus some privacy protections, on a daily basis? Not really, you mostly only know your privacy is being invaded when it's too late.
Compare that with how your life as a gun owner changes if, say, conceal and carry is revoked. Or AR15 rifles are banned. You experience that immediately.
Also, good luck getting celebrities on board. They are used to having their privacy violated as a matter of routine. For them to experience a real change in privacy would involve infringing on certain First Amendment rights (look up the difference between public and private figures)
