The current rhetoric of the group known as “Israeli Charedi writers” is that of walls, crenellation, forts, etc. DIY ghetto walls, to keep the barbarians out (Jew or otherwise). By the way, my own, unproven, impression is that this imagery’s usage has increased ever since the lower-level secular writers started pointing this out.
Jews presently ought to have the kind of confidence in the justice of their cause that drives our enemies to build walls. Go on the offensive. Make not the religious unashamed to do good but the anti-religious ashamed to do bad.
To see the same idea put in rabbinic Hebrew, see this recent post.
