On the one hand, I don't disagree that these are worrisome times on a public relations level... but on the other hand, emotional people are also far more likely to overplay their hand than rational types. I think we're already seeing the early signs of that on a national level.
For instance, the more David Hogg hurls wildly misinformed, arrogant statements, the more he's starting to rub a lot of conservatives, moderates and even some progressives the wrong way. Despite the sympathy that adults naturally feel for a traumatized kid, it will bump up against the fact that no adult much likes a know-it-all teen... particularly one with such astounding hubris and withering disdain for adults. My attitude is shifting to: oh, please... do let Mr. Hogg keep talking!
Further, the retired SCOTUS judge calling for repeal of the 2A? He, too, may have done us a favor! He's got all the liberal networks babbling about it round-the-clock... panels of "experts" that can barely wipe the spittle off their chins, they're so overly excited about the thought of repealing the 2A.
The gun-haters are finally getting just bold enough to say how they really feel. They're not hiding behind their usual platitudes of "we support the 2nd amendment, BUT..." Nope, they're laying it right on the table. You don't think this is going to bring gun owners out to the mid-terms in droves? There's an estimated 80-100M gun owners in this country, spread across roughly 44% of households: they're hearing and seeing all of this... they know they're being unfairly demonized all over the airwaves, the TV and the Internet. The resentful backlash may well be enough to squash any "blue tide" that's been rising. The anti-2A side may be metaphorically "shooting themselves in the foot". I'm not saying we should sit back and relax... I'm just saying that all of that "emotion" could end up backfiring.
In the meantime, in NJ, the focus will be in the courts. I agree with @JC_68Westy 's point above... and one made previously by @capt14k also. But, better yet, maybe that's a way to harness NRA, ANJRPC or another 2A org to support that? Like how about a series of workshops on how to file your own case... with recommended language, templates, etc.? Thousands of cases hitting them all at once looking for FULL, MARKET RATE reimbursement on anything made illegal... with at least some individuals willing to carry it through to higher courts as well. Swarm them like a bunch of hungry mosquitos at dusk.
