Gun laws in the USA would not be as friendly to the gun owner if the NRA was not around.
The good they do does not mean they should not be criticized when it's appropriate. In this case, it looks a lot to me like the NRA is getting special treatment, and is willing to abandon smaller groups, such as the SAF.
Considering the NRA's initial reaction to the Parker/Heller matter
, I'd say we need the non-mainstream groups at least as much as we need the NRA.
