In open battle, when you attack an established position, incremental advances are of little or no tactical significance. You take the position; you drive your enemy from it. If you cannot do so in short order, you retreat.
Take Gettysburg. On Day One, Ewell et al. made advances against the Union positions that Buford and Reynolds had established. But the Rebels needed to do more right then, before more Union forces could arrive to reinforce the Federals’ (excellent) position, held by Hancock. The Confederates did not; and so all their gains that day went for little to no tactical advantage.
To apply this principle to the aptly-named culture wars of today: conservatives need to stop being surprised or offended at the zeal and audacity of the so-called Social Justice Warriors. At present the culture wars are not in a quiet season where incremental, strategic stealth maneuvers are the order of the day; this is a moment of open battle. Whatever one thinks of the aims or strategies of SJWs, we cannot misunderstand their tactics, which as tactics are eminently rational. They are doing what all forces that assault established positions must do, what the Confederates should have done on Day One at Gettysburg: press for swift and total victory while the momentum and conditions are favorable. For when the ground is against you, you cannot take the chance that the weather might also turn against you, or that Hancock might receive reinforcements.
