"Conservative" means different things at different times and in different places. Hot-button "liberal" and "conservative" issues come and go, and switch sides. The words change meaning, the politicians change parties, the parties change their platforms.
The NRA would be worse than useless if it got caught up in all these other political disputes. By taking sides, it would alienate some people and attract nobody. By using up time, money and political capital, it would destroy any possible effectiveness the NRA has with RKBA issues. RKBA has to stand on its own as an issue, no matter what label it gets on any given day, and so does the NRA if it wants to have any success at all.
Does anyone REALLY think the NRA would be more effective
as a gun-rights organization if it got caught up in the politics of: stem-cell research, bank bailouts, gay marriage, changes in the tax code, energy policy, military spending, Medicare compensation, school prayer or any of the myriad other things that are in the news today, forgotten tomorrow, and in the news again the day after? Some of them may seem important at the time, too, and then seem totally stupid soon after.
It doesn't matter which side of any of these issues you find yourself on, or if you are ambivalent. I think it is very clear that the NRA would only stand to lose effectiveness in working for gun rights, and alienate people who could be allies or members, if it picked sides in all or any of these other issues.
Really. Take a breath, and think it through for a second.
It's no fun being a grownup, though, is it?
