There have been a number of those "pro 2A" groups, some of them small but OK, others simply a way to let the one or two "founders" pocket the money. Some, especially those with "sportsmen" in the name, have been fakes, set up by anti-gun groups or candidates to take gun owners' money while actually promoting the anti-gun cause. The fakes, the false flag groups, are easily spotted. Even the most extreme, frothing at the mouth, "ban guns" candidate will create a "gun owners for X" or "sportsmen for commonsense gun laws" or something similar. Don't fall for them.
But even the small groups divide our support. Some people, for reasons they believe are good, don't like the NRA. But a contribution to a one-man pro-gun group gets us nowhere. If he testifies before Congress, the antis know well that he has no clout, that he is mouthing off to hear himself talk; he is ignored or is the butt of jokes. One way some of those those "groups" get funds is to lie about the NRA, claiming it is a tool of the rich; part of a government conspiracy; working for the millionaire gun makers; covering up for or even part of organized crime; covering up for defective guns, which blow up and kill people by the millions, etc.
My take: Yes, the NRA can make mistakes and has done so. But they are the only real game in town on our side. If you won't join or contribute to them, that is your choice. But stop lying about them and talking trash to those of us who are members and support them.
