Of course they have not. That's why the .gov has an edge, just like any other group with a fat bankroll to pay flesh-eating lawyers.
Hell, in an episode of the Sopranos, Tony and a black musician/gangsta were in dispute over ownership of a song. Even THEY went to the lawyers, not the mattresses!
To push for civil rights, you need:
1) belief in the righteousness of your cause
2) support of, if not the majority, at least a large enough minority, or a coalition, to be takes seriously
3) a long-term strategy that all in the group/coalition will stick to, at least in broad strokes
4) the willingness to take lumps, either real or figurative, for the cause....until you get the result you want
The gays did it right: 25 years ago, they stayed in the closet, mostly, or in "special" places like P-town. Then they started chanting, "We're here...we're queer....get used to it."
They believed that they were right; they got a coalition of people to join them; they kept at it; they kept marching, faced down the people that hated them, and the big bunch of people that are not gay, but also don't really care if
you are said, "Meh."
It was the same playbook as the blacks used in the 60s...and they took
real lumps.
Why won't it happen here, in the Gun Culture?
1) we're too fragmented - Fudds don't see that AR owners are the same, and vice versa
2) American culture is too sharply divided over guns - to be on Team Gat, you need one (generally), when with other causes, you can support without participating (lots of straight people marched with the gays), so a coalition is tough to build
3) the long term strategy is to bail, not sail the ship, as we're fighting a holding action
4) most gun owners have too much to lose, in their lives, to be test cases (witness the couple that stood outside their house, armed, while the "demonstraters" marched by. Most here see that as, if not prudent, then understandable...and they're in a pile of crap.
The real problem is that the majority of law-abiding gun people are too law-abiding to push the envelope.
