I'll bite.
As a recent gun rights supporter, I've gone from ambivalence to the NRA, to basher of the NRA, and now back to support of the NRA.
I see them as the 850lb gorilla of the gun rights lobby. (Yes, gun rights is a lobby, but thats only because our politicians can't read the US Constitution and BoR.) The NRA has the ear of a lot of people in power, and they know what is possible and what is not. They also know what will turn the undecideds away from us and what will turn them towards us.
Its only recently, IMO, that they have started on the path of incrementalism. The gun ban lobby have known this all along, and have used it against us to great effect. Thats because we have compromised with their proposals, and we have not made proposals of our own. But this has changed, and there are quite a few proposals that our side have made and won.
The NRA has always been about gun safety, gun education. It still does these tasks, but now, it has had to be about gun rights. Prior to that, I think that NRA was on the defensive when a new gun law was passed, it kept trying to see which group was affected by it, and it if it wasn't the majority of its members, it would not push as hard.
What happened recently is that Clinton happened. Clinton was the best recruiter for the NRA. His gun grabbing hands made a lot of gun owners, gun owners who started by owning black ugly guns sit up and take notice. They started joining the NRA in spades. Some of these people really got involved in the NRA, and started applying for and becoming NRA directors. This ends up changing the stance that the NRA takes, and its now starting to become a more strident gun-rights lobby. Plus, NRA directors are usually there for quite a long time, and its usually name recognition that gets them elected. It takes time to develop that, and I would bet that only recently have the balance of NRA directors shifted from hunting/sporting-minded ones to self-defense/gun-rights-minded ones.
It has also taken the emergence of other gun rights organization, like GOA, and JFPO, and others to make the NRA sit up and take notice.
I'm a life member too, but I think that I'm more of the self-defense/gun-rights stance instead of the hunting-minded ones. I would like to see this gun control stuff go away, all the way back to before NFA34. I think that the people bashing the NRA are like me. They just want to see more action from the NRA.
