Those who cannot learn from history are doomed to repeat it.
I think you can start to understand suicidal empathy by looking at the Iranian Revolution.
During the late 1970s, a wide coalition of groups including Marxists, liberals, Islamists, and students opposed the Shah of Iran, who was supported by the US and seen by this coalition as a Western puppet. Many Western leftists viewed the Shah's regime as imperialist and authoritarian, and therefore cheered the Iranian revolution as a people's uprising.
Ayatollah Khomeini, a Shi'a cleric, became the symbolic leader of this revolution.
Western leftists, in solidarity with the anti-Shah cause, downplayed or misunderstood Khomeini's theocratic intentions, viewing him instead as a symbol of anti-imperialism.
But Khomeini was an aspiring theocrat. Once the Shah was overthrown, Khomeini's Islamists turned on their secular and leftist allies.
Marxists, feminists, liberal democrats, and secular nationalists were imprisoned, executed, or exiled. Women were forced to wear the hijab, and Islamic law replaced secular codes. Political dissent was brutally crushed, often much more harshly than under the Shah.
The naïveté of Iranian leftists who had supported the revolution without recognizing the reactionary, theocratic nature of the movement they were backing? That's where the Western far left is going. That's suicidal empathy.
Suicidal Empathy is a form of excessive or uncritical empathy which leads individuals or groups to support causes, ideologies, or people whose core values may be fundamentally opposed to their own...and ultimately to their own detriment or destruction.
This kind of empathy becomes suicidal when it results in self-destructive alliances or compromises, often in the name of tolerance, anti-imperialism, or social justice.
Suicidal empathy helps explain the paradoxical support of Western leftists for radical Islamist movements which despise them as articles of faith.
So...why do such leftists support Islamists who would cheerfully murder them?
1. Shared Anti-Imperialist and/or Anti-Western Sentiment
Many Western leftists are deeply critical of Western foreign policy, especially U.S. and European military interventions in the Middle East. Islamist movements, particularly militant ones, also oppose Western influence. This shared opposition to "imperialism" can create a strange bedfellow dynamic.
These Leftists see Islamist resistance as part of a broader struggle against Western hegemony.
But this overlooks the reactionary social values of many Islamist groups, which often include patriarchy, homophobia, anti-Semitism, and authoritarianism - values that sharply contradict progressive ideals.
Some leftists adopt a framework where oppression and victimhood define moral authority. Since Muslims, in the context of global leftist politics, are often seen as victims of Western aggression, there's a tendency to uncritically sympathize with Islamist movements under the assumption that they are inherently oppressed, regardless of evidence to the contrary.
So when Islamist ideologies are anti-liberal or even fascistic...they may still be viewed through a lens of victimhood rather than agency.
3. Cultural Relativism Taken to an Extreme
Many leftist thinkers promote cultural relativism not as an academic principle, but as a living practical policy doctrine. The fear being labeled as Islamophobic if they, for instance, acknowledge the atteocities of female genital mutilation, honor killings, child brides, slavery, and theocracy. So they avoid criticizing reactionary, regressive, barbaric aspects of Islamist ideology, even when these violate their own principles (e.g., women's rights, LGBTQ rights, free speech).
In defending "cultural practices" under the banner of tolerance, they tacitly support values that would call for their own deaths. "Suicidal empathy," indeed.
The legacy of colonialism leads many in the Western left to feel deep guilt over historical injustices. This can fuel an overcorrection which leads them to defend or romanticize "resistance" movements, even when these movements uphold values that are themselves oppressive and regressive. (Bizarrely, their guilt over colonialism never finds expression in US leftists organizing en masse for Native American Indian nations. Canadian leftists haven't given nearly the energy to the needs of First Nations people's that they've given to Palestinians. No leftist movment in support of Australian aboriginal peoples has ever gotten the energy from Australian leftists that Palestinians enjoy. Why? Because by condemning and sacrificing Israel for their sins, they get to feel righteous without having to know or sacrifice bupkis.)
And this works against actual human rights efforts.
This alliance enables authoritarianism and suppresses genuinely progressive voices in many Muslim-majority societies. Secular Arab liberals and feminists often express frustration that Western leftists support the very Islamist movements they struggle against at home.
Suicidal empathy comes from well-intentioned, dangerously naive solidarity that prioritizes identity, victimhood, or anti-imperialism over consistent moral principles. The alliance between Western leftists and Islamist movements becomes "suicidal" when it undermines the very values the left claims to champion-like human rights, secularism, and gender equality.
The Millennial and Gen Z protestors calling for Israel to be destroyed? That's where they're headed.
I think one of the reasons we're having massive political realignments all of the world right now is because many are starting to realize that shared enemies ≠ shared values.
I hope the campus leftists figure it out soon.
