The NRA are the squishy moderates of the Pro-Gun crowd.
The NRA has a past record of being willing to "compromise" or, if you go back far enough, straight up sponsor gun control (See the 1934 National Firearms Act). The NRA, in fact, has a very strong contingent of "Fudds"*, and WILL accept some gun control - although we're pretty close to the limits they'll tolerate, and it's quite rare for the politicians to propose the sort of gun control that the NRA would be willing to support.
Of the other major pro-gun groups, almost all of them are significantly more hard-line than the NRA - for example, Gun Owners of America (GOA) which emphasizes their "No Compromise" stance on gun control. Don't make the mistake of thinking that all those gun owners who aren't in the NRA are going to side with you. Oh, some of them will - there are plenty of Fudds who don't even care enough to be in the NRA - but many, perhaps even most of those gun owners view the NRA as being anything from "good, but not enough" to "barely better than quislings".
So the next time you complain about the NRA blocking a piece of gun control, you might want to consider something: Why are the Squishiest, most moderate of the gun owners opposing this? If the moderates on the "pro-gun" side are so worked up about "common-sense gun legislation", how do more extreme groups feel? Are they actually serious about "from my cold dead hands"?
*Fudd, a hunter/recreational shooter of a single gun, who supports or fails to oppose most gun control for a variety of reasons including:
- They don't think that their gun will ever be banned
- They believe ownership of firearms should be limited to hunting weapons
- They just don't care
- Rank hypocrisy.
