“Intersectionality,” the beast born in liberal hothouses on college campuses, slouches now toward the halls of power. It is a Marxist notion that all discrimination is linked because it is rooted in the unjust power structures that facilitate inequality. Therefore, there are no distinct struggles against prejudice. Class, race, gender, sexual identity; these and other signifiers are bound together by the fact that oppression is institutional and systemic. The problem with this ideology is it compels its adherents to abandon discretion. To sacrifice anyone with a claim to oppression is to forsake every victim of prejudice. So, sure, Assata Shakur robbed, assaulted, incited violence, and killed a cop. But she also hates capitalism and white supremacy. Therefore, she’s one of us.

It is this logic that has rendered the “Sister Souljah moment” a relic of the past, and The Resistance is drowning in Sister Souljahs.

One of the March organizers, Linda Sarsour, has enjoyed newfound popularity and legitimacy in the age of Trump. She is a self-styled organizer for civil rights and the Muslim-American community of which she is a part, and she’s been acclaimed by organizations like the ACLU and Demos. Democratic Senator Kirsten Gillibrand described Sarsour and her colleagues as “the suffragists of our time.” In return for this lavish praise, Sarsour has only forced her defenders into awkward positions.

Sarsour has praised Saudi Arabia’s social welfare state as appropriate compensation for stripping women of privileges such as driving a car. “I wish I could take their vaginas away,” she wrote of women like the Somali-born Dutch-American activist and genital-mutilation victim Ayaan Hirsi Ali. “You’ll know when you’re living under Sharia Law if suddenly all your loans [and] credit cards become interest-free. Sound nice, doesn’t it?” she asked. While delivering the keynote address to a Muslim-American conference, Sarsour advocated “jihad” against Donald Trump, defining the term to mean only speaking truth to power. Rather than admonish their political ally for this obvious indiscretion, the American left went to the mattresses to explain that only they understand the true meaning of the word “jihad.”

For some on the left, advocating violence is not only justified but fashionable. Misanthropic so-called “anti-Fascist” activists like Shanta Driver and Yvette Felarca have become a ubiquitous presence in pro-Resistance mythology. People like Driver advocate for “militant actions” while Felarca appears at the head of armed mobs “resisting” the white supremacist alt-right “by any means necessary” (which happens to be the name of the organization to which she belongs). For this “activism,” these and other “anti-fa” organizers are feted by left-wing magazines like Mother Jones and The Huffington Post.

Amid the celebration of left-wing political violence, a man who had been radicalized by liberal politics attempted the mass assassination of Republican members of Congress. Far from dwelling on this potentially generation-defining attack, the event passed through the national consciousness like an apparition. We don’t talk about that now. Perhaps we don’t want to think about what it might portend.

None of these individuals have roots in Democratic politics so deep that they cannot be deracinated relatively painlessly. Indeed, their counterproductive behavior would compel any competent political operation to make an example or two—particularly an operation struggling to demonstrate that it can be trusted again to govern seriously and effectively. Yet the Democratic Party and the liberals who animate it have come under the spell of a philosophy that explicitly forbids the exorcism of its demons.

Republicans have their devils, too. The excision of which may not seem a terribly urgent project today, given the GOP’s political dominance. They will confront that crisis soon enough. In the interim, Democrats should be remaking themselves to appeal to the existing electorate; the one that delivered to the GOP near total control of state and federal government over just six years. Instead, Democrats are voluntarily yoking themselves to their most radical elements even as the number of Americans who describe the party as “too extreme” continues to climb.

Republicans may have their troubles, but a competent opposition is not among them.
