According to a recent survey of American social attitudes, approval of polygamy has doubled. How long will it be, Ross Douthat wonders, before plural marriages gain legal recognition?

Can Americans say a permanent “no” to recognizing plural marriage once we’ve rooted for the Browns [the polygamous stars of a popular reality-television show]? Can a cultural left that believes in proliferating gender identities . . . draw the line, long-term, when a lesbian couple wants to include their baby’s biological father in their legal family, or when the child of polygamists stands up in court to say he wants his dad recognized as his mother’s legal spouse? Is a culture where prominent men routinely have multiple kids with multiple wives across multiple decades going permanently to deny marriage rights to people who want the same thing, except all at once? . . .

[I]t’s an interesting question. I feel safe predicting that polygamy will not be legally recognized, with fanfare and trumpets, in 2025. But it might be recognized in 2040, with a shrug.

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
