We didn't lose the 2nd amendment overnight, and likewise we wont reinstitute the whole 2nd amendment in one bold effort. (Or as Gene is saying; By being absolute on principle, when such principles are not congruous to our current political and legal reality.)
In California, the 2A was whittled away in tiny, easy to digest portions seasoned with superficially acceptable justifications. Beginning with addressing the problem of Latinos and Chinese carrying concealed handguns- then later, to address the problem of African Americanes armed with loaded shotguns and rifles. The only thing that has changed in the bigotry that is being imposed on us, is that the legislature is able to discriminate on a colorless minority under the pretense of public safety.
I would say however, that strong interest in or support of gun ownership continues to be the driving motivator for anti-gun legislators. They propose laws, because they see something that they feel must be reigned in, something that they cannot regulate fast enough to maintain their ideal status quo. If there were little or no interest in guns and gun ownership, they would feel no need to propose new regulations. This is where we got AB1934 and AB144 - because the interest was strong enough to feel in Sacramento.
The good news is that no matter how strong Sacramento is, there is Kryptonite that makes every new effort to reduce the 2A weaker.

How we win in California is by creating new gun owners of an unassailable demographic. If we regularly take up the responsibility of passing on our 2A legacy, we will eventually make the anti-gunners push back with new law... unless it makes them look like the bullies and bigots that they actually are.
