When “cancelation,” in the sense of public shaming and exile from polite society, first entered Americans’ vocabulary, it was a phenomenon limited to celebrities. Since then, even ordinary people have lost their jobs or suffered other real-word consequences for the slightest infractions. And although the cancelers have become adept at doling out punishment, there is yet to be an equivalent process of rehabilitation or absolution. David Wolpe, contemplating the case of a friend who has been “canceled”—with good reason, in Wolpe’s evaluation—looks to what Yom Kippur, a holiday of forgiveness, can teach our unforgiving culture.

There will always be things we cannot fully forgive and people who do not deserve to be restored to good reputation. And forgiving someone does not necessarily mean readmitting that person to your life. In most cases, however, Jewish teachings insist that fair judgment does not require damnation.

Judaism offers a series of ideas and guidelines for how to cope with offense and foster forgiveness. On Yom Kippur, it’s traditional to wear white, not only because white shows the slightest stain, but to remind us of the shrouds in which we will one day be buried. We do not have forever; we must struggle to right our souls now.

The Hebrew word for repentance, t’shuvah, also means “return.” To repent is to return to what once was, what became hidden through coarseness or impulse. It is also to return to God and to the community. But slow, careful restoration takes time. The one who is sorry today and expects to stride right back, unblemished, is naïve or conniving.

Public shame is a powerful and sometimes necessary punishment. . . . But it can also be brutal, and I believe that too often, lifetimes are remembered by their worst moments, and complex personalities reduced to their basest elements.

If there is to be peace, Palestinians will have to unlearn the hatred of Israel they have imbibed during nearly two decades of Hamas rule. This will be a difficult task, but Cole Aronson argues, drawing on the experiences of World War II, that Israel has already gotten off to a strong start:

The population’s compliance can . . . be won by a new regime that satisfies its immediate material needs, even if that new regime is sponsored by a government until recently at war with the population’s former regime. Axis civilians were made needy through bombing. Peaceful compliance with the Allies became a good alternative to supporting violent resistance to the Allies.

Israel’s current campaign makes a moderate Gaza more likely, not less. Destroying Hamas not only deprives Islamists of the ability to rule—it proves the futility of armed resistance to Israel, a condition for peace. The destruction of buildings not only deprives Hamas of its hideouts. It also gives ordinary Palestinians strong reasons to shun groups planning to replicate Hamas’s behavior.
