One need not be an ardent Thatcherite to argue that these have historically been prerequisites for peaceful, sustainable and equitable societies. For much of post-World War 2 Western political and economic thought, this was the orthodoxy.

Debates and reforms around policy and ideology – essential parts of liberalist philosophies – tended to operate on where one positioned oneself on the market-versus-state continuum, from north European social democratic liberalism through to Reaganist market fundamentalist libertarianism. These were healthy and vibrant debates of degrees and extents, not ham-fisted narcissistic confrontations.

How things have changed. It is no surprise to see that liberalism is under attack from “outside”. China has branded it decadent and unstable, while Vladimir Putin has been even more explicit, exclaiming that “liberalism has become obsolete, it has outlived its purpose”, in a now-famous interview with the Financial Times.

But what is surprising is that liberalism is under attack at home and indeed from within western political establishments.

Nowhere is the fight fiercer than in America where, clearly, it is the Trumpian right that is its most dangerous threat. Such populists vilify cornerstones of liberal thought (such as science and the rule of law) as elaborate façades of the deep state against “the true people”. Liberals, a term that seems to have no correlation at all to the original meaning of classical liberalism, are branded as enemies of social order itself.

However, it is the left – also dubbed the “illiberal left” – that has started to denounce those same tenets. Seemingly spreading from elite universities, graduates have taken ideological purity and an agenda obsessed with a narrow vision of obtaining justice for oppressed minority groups as being more important than the principles of liberal thought. It is not through “cancelling” those with whom one does not agree that liberal ideas can flourish; indeed, quite the opposite is essential for the liberal reforms and debates on which social development is predicated. A “confessional state” is merely the flip side of the same populist coin as Trump.

Milton Friedman once wrote, “a society which puts equality before freedom will end up with neither”. He was right. So the question must be, why has this happened?

Seemingly, it is this reactive world we live in where populists and progressives feed off each other’s misguided arguments. There is no room for pragmatic policy-based discussions – you are either in my camp, or in the other, all while the hatred that each tribe feels for the other inflames its own devotees.

In similar ways, liberals in South Africa find themselves at a moment of intense crisis. South Africa, clearly, has had a complex and largely fractious relationship with liberalism, such is the reality of the South African political economy. But that does not discount the important role liberals have played throughout the modern history of South African politics and economics.

Before democracy, it was the liberal agenda of the Progressive Party of Helen Suzman and Frederik van Zyl Slabbert, who were the only opposition to apartheid in Parliament.

In the 1990s and early 2000s, the hard-line Westminster-style liberal tactics of Tony Leon that ensured free markets, privatisation and making SA a business-friendly destination for investment were topics of discussion. Although they were not times of agreement between the DA and ANC, at least they were moments of essential debate.

All of which makes the paucity of such discussions from contemporary South African “liberals” eminently depressing. The DA, which should be championing what many South Africans want – the rule of law, respect for individual rights, an open-market economy conducive for growth and restrained government interventions – seems to have sacrificed such levels of debate for the fleeting temptations of the dark and dingy cesspit of Twitter and vicious infighting.

The disputes over billboards in recently traumatised parts of the country indulging in what can only be called racial vote-baiting is the most recent and extreme example of that – the “wokerati” progressives against the “true” liberalist populists.

Van Zyl Slabbert and Suzman would surely struggle to understand and recognise what has happened to these self-appointed heirs of the South African liberal tradition. Sadly, as in so many parts of the world, the battle of true South African classical liberals has never seemed harder.

This remains a cause worth fighting for. A sizeable portion of voters in the western world and indeed in South Africa – from across all parts of society – surely agree that it is the very least they can expect from their political representatives. DM168
