The recent massacre of Muslims in Aotearoa/New Zealand by white supremacist terrorist Brenton Tarrant must, I think, be seen as the latest morbid symptom of world capitalism's death drive - its descent into barbarism. The poisonous bulletin board messages on cesspit websites such as 8chan no doubt played a big part in reflecting and reinforcing Tarrant's abhorrent beliefs. And along with other social media platforms, Facebook, which inadvertently hosted Tarrant's livestream of the event, is on the backfoot, as several corporations threaten an advertising boycott of the platform. But if any quarter of the mainstream media world should feel ashamed after Christchurch, it is surely the right-wing tabloid press. It is all very well for The Sun identify Tarrant on its front page as a 'Facebook Terrorist', but the tabloids must bear at least some responsibility for the Christchurch carnage, having spent years decrying Muslims as thugs, fanatics and sexual groomers.

That said, even right-wing journalists and politicians described the Christchurch killings relatively respectfully in the hours after the attack: The Express, one of Britain's most malicious anti-Muslim newspapers, went with the headline 'Hate-Fuelled Attack on Values That Unite Us All'. This was sheer hypocrisy, of course; but when a hundred people have been killed or injured by an Islamophobe with views about society very similar to your own, it's probably best to wind your neck in until the dust settles.

A few right-wing rabble-rousers, however, were undaunted by considerations of taste or timing. Australian senator William Fraser Anning, in particular, saw an opportunity to make a splash, blaming the atrocity on the "the growing fear within our community, both in Australia and New Zealand, of the increasing Muslim presence". He was widely condemned - and rather deftly 'egged' - for his bigotry. But British blabbermouth Katie Hopkins - a woman ever keen to fan the flames of social discord - waded in to defend Anning in a bizarre video rant posted on twitter, in which she expressed more concern for the media's supposed depreciation of 'whites' than for the victims of the attack.

Mainstream politicians and media commentators, meanwhile, took a different tack. Many of them went wild for New Zealand's Prime Minister Jacinda Ardern, after the latter showed a degree of sympathy for the victims lacking among more conservative pundits. In The New York Times, for example, Sushil Aaron wrote an article entitled 'Why Jacinda Ardern Matters', hailing the PM as a "progressive antithesis to right-wing strongmen like Trump, Orbán and Modi". And in Britain's Guardian newspaper, Suzanne Moore opined that "Jacinda Ardern is showing the world what real leadership is: sympathy, love and integrity" and even went so far as to claim that Ardern "has given us a vision of a better world". Many ordinary people seem to have been caught up in this Jacinda-mania, too: memes depicting a sorrowful Ardern wearing a hijab have been circulating on social media, captioned with lofty panegyrics to her compassion and - that word again - leadership. But the height of absurdity was reached in a letter co-signed by British Labour politicians Jeremy Corbyn, John McDonnell, Diane Abbott and Emily Thornberry, which praised Ardern as "an inspiration to the international working-class movement".

We should absolutely reject this lionization of Ardern. A former advisor to Tony Blair - a man hardly famed for his contribution to world peace - Ardern is known for her policy of reducing immigration into New Zealand. Together with its far-right coalition partners New Zealand First, Ardern's Labour Party has been whipping up anti-Chinese xenophobia and racism and New Zealand's military forces have played their part in the wars in Afghanistan, Iraq and elsewhere.

Indeed, while much of the press in New Zealand have argued that Christchurch signals an 'end of innocence' for the country, New Zealand was already fully implicated in the horrors of imperialism and its Prime Minister, like any other capitalist politician, represents a system of nationalism, exploitation and alienation that cannot but give rise to regular explosions of war and terrorism across the globe. Atrocities like Christchurch perfectly reflect the necropolitics (Achille Mbembe's term) of the contemporary nation state, its formidable power over the very existence of black and brown civilian bodies. Faced with events like these, then, we would do well to reject both the racist nationalism of deranged xenophobes like Tarrant and the hypocritical condemnation of it by world leaders. What neither the liberal nor the right-wing media can acknowledge is that only way of halting racist violence, of banishing the scourges of social antagonism, fear and alienation, is for working-class people to come together - peacefully if possible - to end the system that causes them.

"Although it ain't no party, you're dying to get in" - David Byrne, 'The Civil Wars'

The right-wing and tabloid media reaction to the ongoing refugee situation in Europe has been predictable enough. In July of this year, the breakfast TV cockalorum Eamonn Holmes bemoaned how 'everybody' is 'pussy-footing' around the migrant issue, suggesting that electric fences be used to keep them away. Holmes was not a lone voice. Back in April, Sun columnist Katie Hopkins boldly recommended using gunships to stop the migrants, whom she described as 'cockroaches'. This turns an entry from Winston Smith's diary in Orwell's 1984 ('Last night to the flicks. All war films. One very good one of a ship full of refugees being bombed somewhere in the Mediterranean') into a policy suggestion. And Hopkins is seemingly valued for her controversialism: she is currently enjoying more public exposure - and no doubt financial remuneration - than ever, and now hosts phone-in programmes on LBC radio.

That Hopkins can be allowed to continue as a high-profile media commentator indicates the astonishing callousness of public attitudes to the most desperate global others. Something of this callousness is reflected in the recent British zombie film The Rezort, in which it is discovered that a corporation, with the help of a humanitarian organization, is deliberately turning refugees into zombies to be shot at and abused in a kind of undead theme park.

Day after day throughout this summer, meanwhile, the Daily Mail has been wailing about the 'tides' and 'swarms' of immigrants entering Europe. Even the BBC is getting in on the act. In recent weeks I have heard BBC radio journalists refer to the 'flooding' of migrants into Europe. One Radio 4 journalist, on the very same day that David Cameron was criticized for talking of migrant 'hordes', referred to an 'influx'. Well, here is a picture - one of several banned by Facebook - showing what an influx looks like when it hits the beach. This girl was one of several Middle Eastern children washed up on a Libyan shore, seemingly after a failed attempt to reach Europe via the Mediterranean.

In recent days, some of these pictures have been circulating on social media and even in mainstream news media, although notably the images that have gained most mainstream traction have been the photographs of a drowned Syrian boy, Aylan Kurdi, being removed from a Turkish beach. That the Aylan Kurdi photographs have circulated widely in the Western media suggests that there has been a shift in what is representable, although the distancing involved in the long shot photographs of Aylan may suggest that humankind cannot take very much reality (and as some observers have noted, Kurdi appears in the photographs more like a white, European child than the children on the Libyan beach, raising the question of whether Western humanitarian reactions have a racist aspect). Nevertheless, as public consciousness of the scale of this suffering grows, and as ordinary people across Europe mobilize to assist the refugees, much of the mainstream media seems to have been forced to tone down its dehumanising discourse.

Yet the priorities of the capitalist media are fundamentally unchanged. Although The Sun has of late adopted a more sympathetic tone, a recent editorial nonetheless calls, absurdly, for the closure of borders and the (further) bombing of the Middle East as 'solutions' to the refugee crisis. And by failing - or perhaps we should say refusing - to articulate the structural causes of this tragedy, the news media demonstrate what the sociologist Chris Rojek calls 'event consciousness', separating event from process and framing humanitarian emergencies as singular happenings unconnected with wider social and economic processes.

This de-contextualization should be resisted and the origins of these horrific events should be made clear. The roots of today's refugee crises lie in the crisis of capitalism, with its increasingly militarized borders, refugee-creating wars and socio-economic chaos. Capitalism is a deadly and inhuman system: according to its logic, only employees (who can be exploited) and consumers (who can raise profits) exist. Any project aimed at ending capitalism, by contrast, must embrace all of humanity, recognizing and empowering those who, from the point of view of the current social order, do not exist.
