If the American gun business stays on its present course, its market will likely continue to consolidate into the hands of a smaller, more dedicated community. That will widen the gap between those with a “combat mind-set” and those without, between “friends” and “enemies.” If Donald Trump reaches the White House, he will bring with him a moral logic of concealed carry. If he falls short of the Presidency, his admirers will have gained, at a minimum, fresh evidence of their encirclement. As the pro-gun and the anti-gun worlds grow further apart, it gets harder for each side to understand the intentions of the other. They are, more than ever, like two groups squaring off in the dark, convinced that the other wishes them harm.
