This article by Nick Cohen appeared in the leftist, anti-Semitic, Islam-loving Guardian. And yet – except where we have raised a few objections – it is an opinion we find we can welcome.

No one could have predicted that the Bangladeshi writer Rafida Bonya Ahmed would make it to London last week. That she is alive at all is a miracle – to use a word of which she would thoroughly disapprove. As I watched her deliver the British Humanist Association’s annual Voltaire lecture , I saw a dignified and principled intellectual it was our duty to emulate and defend. I could not understand why anyone would want to harm, let alone kill, her.

But many do. In February, Islamist fanatics hacked her husband, Avijit Roy, to death with meat cleavers as the couple left a book fair in Dhaka. They nearly killed Ahmed too: slicing off her thumb and covering her body with wounds. To hear her talk about her murdered husband made me long to have met him. He was a typical intellectual – hopeless with anything practical but in love with literature, science and free debate.

Together, Ahmed and Roy ran a secular blog that promoted the writings of young liberal Bangladeshis They wrote on evolution and humanism; they condemned extremism fearlessly, as the title of Roy’s 2014 book The Virus of Faith makes clear. Seeing and fearing a courageous opponent, the enemies of free thought killed him for his ideas.

Ahmed talked about how compromised the Bangladeshi state had become, and you could easily make the mistake of thinking her story had nothing to do with us. Yet there were guards at the doors of her lecture room, searching bags for bombs and guns. A widow, still recovering from the slash of meat cleavers, with no weapon to threaten anyone beyond the power of her thought, is as much a target in London as Dhaka.

The comparisons don’t stop there. Immigration has meant that Bangladeshi politics are British politics too. You will never understand why London’s East End returns politicians as grotesque as George Galloway or mayors as bent as Lutfur Rahman unless you know that Tower Hamlets is Jamaat-e-Islami’s British stronghold. Grasp that the party of Bangladesh’s religious right is always willing to lend its vote bank to politicians who bow before its prejudices and you will gaze on the East End’s fetid politics with less bewilderment.

A bit of an annoyance there: “Bangladesh’s religious right”.

Religious Muslims are intolerant. Islam is intolerant. It is not surely a matter of “right” or “left” in an Islamic country, but of religious or not religious, and so intolerant or tolerant.

Above all else, the fear that religious terror brings, the lies it makes people tell and concessions it forces them to make are as familiar here as on the subcontinent.

Ahmed was in despair about Bangladesh. Islamists had not only murdered her beloved husband, but two other atheist bloggers. As Bangladesh’s ruling party is officially secular, and as Islamists have opposed the state ever since Jamaat-e-Islami death squads collaborated with the Pakistani army in committing crimes that came close to genocide during Bangladesh’s 1971 war of independence, the naive might assume that the government would be keen to fight her husband’s enemies.

Not so. After one prominent Jamaat activist was sentenced to death for his part in the 1971 war, Islamists responded by demanding that dozens of secularists who had allegedly “insulted” their famously thin-skinned religion be tried for blasphemy and condemned to death. The state did not reply that Bangladeshis had the freedom to believe what they wanted. It said the authorities would prosecute blasphemers under repressive laws that date from the British empire.

But were not made by the British!

Liberals in Bangladesh are therefore on both Islamist death lists and police arrest lists. If killers with meat cleavers don’t get them, cops with warrants will. To Bangladesh’s shame, the state has threatened friends and allies of Ahmed and Roy with prison for the crime of “hurting religious sentiments” and jeopardising “communal harmony”.

Lenin said: “The capitalists will sell us the rope with which we will hang them.” Islamists must feel the same about the “moderate” governments they want to destroy. Instead of taking extremists on and upholding human rights, Bangladesh justifies extremism by turning on the liberal critics of religion and treating them as criminals. In one of the most pathetic interviews you’ll ever read, Sajeeb Wazed, the son of Sheikh Hasina told Reuters that his mother had found it prudent to offer only private condolences to Roy’s family after his assassination. Although “we believe in secularism”, the wretched man explained, the prime minister could not make a public stand “because our opposition party plays that religion card against us relentlessly, we cannot come out strongly. It’s about perception, not about reality”. …

Avijit Roy lost his life because he wanted to change reality, not perception. He knew the dangers, but knew too that there are fights that cannot be ducked. “Those who think victory will be realised without any bloodshed are living in a fool’s paradise,” he wrote before his death. “We risk our lives the moment we started wielding our pens against religious bigotry and fundamentalism.”

Compare the bravery of Bangladeshi intellectuals with the attitude of the bulk of the western intelligentsia. Whole books could be written on why it failed to argue against the fascism of our age – indeed I’ve written a couple myself – but the decisive reason is a fear that dare not speak its name. They are frightened of accusations of racism, frightened of breaking with the consensus, frightened most of all of violence. They dare not admit they are afraid. So they struggle to produce justifications to excuse their dereliction of duty. They turn militant religion into a rational reaction to poverty or western foreign policy. They maintain there is a moral equivalence between militant religion and militant atheism.

We agree. There is no moral equivalence between militant religion and militant atheism. There is no moral equivalence between religion, which is the propagation of lies, and atheism which condemns the lies.

On occasion, they drop even that spurious attempt at evenhandedness and seem to suggest, as Professor Craig Calhoun, director of the London School of Economics, did recently, that the real menace facing universities is not students heading to Syria to rape and behead but secularists whose calls for free speech “challenge the faith and beliefs of religious students” and disrupt “campus harmony”. David Cameron will clearly have trouble taking his mission to “root out” extremism to the LSE.

For all the similarities, there is no moral equivalence between Britain and Bangladesh. They have thinkers of the calibre of Rafida Bonya Ahmed and Avijit Roy, while we have liberals whom Karl Marx might have looked at and said: “Religion is the opium of the intellectuals.”

But Marxism is another religion.
