You may be right that guns are are corrosive to a democratic society, that's an open debate. But the people who depended on that factory had the rug pulled and real harm was done without any regard to their welfare. And not everyone who depended on the factory worked there, deli owners and dry cleaners, these types of legitimate businesses are damaged when a major employer closes doors.
I suppose I relate this story to you just to show that, there are other people who think like you, guns are stigmatized, and it has a real human cost. We should not be flippant with our neighbor's well being, because we can't predict the turns of fate, one day it might be our turn.
