The pendulum swings because legislators are willing to barter Constitutionally protected rights as bargaining chips against pieces of non-2A legislaton they personally favor. Our rights are not subject to the preferences of legislators. But those same legislators traditionally block any legislation that might curtail their caprice, the media solemnly portray those caprices as 'safety' and universally laud the legislators, and SCOTUS tap dances around getting off their collective butt and making any broad declarations contravening 2A infringements beyond the very narrowest interpretations related to litigation directly at hand. They could, but they collude with the others in refraining from doing so.
Face it, the media, judicial, legislative, and executive policy in this country is surreptitiously committed to emasculate the 2A and render the entire populace defenseless against government excess/oppression, whether real or imagined. Neither of those perceptions are grounds for cancelling out the right of the public to arm and bear for itself according to its own best judgment. In these matters, they are no better than Hitler or Stalin was.
Every time a 2A infringing law is cut into the books, another decision is taken out of the hands of we citizens. That is how the government usurps one's individual Constitutional authority and disenfranchises each and every citizen of this Nation.
Want that? Willing to stand up behind something else? Hope so. If not, maybe it's time to review our man cards; and women are not exempt, either.
