Has Neoliberalism infiltrated both the right and the left? The most coherent and well formulated definition of neoliberalism I know comes from the political philosopher Wendy Brown, who refers to it as the "widespread economization of heretofore noneconomic domains, activities, and subjects”, such that it “extends a specific formulation of economic values, practices, and metrics to every dimension of human life.” Concomitant with this 'economisation of the noneconomic' is, for Brown, nothing less than a redefinition of what it means to be human: "neoliberal rationality disseminates the model of the market to all domains and activities - even where money is not at issue - and configures human beings exhaustively as market actors, always, only, and everywhere as homo oeconomicus.” (Brown, Undoing the Demos). This is pretty close to Monbiot’s understanding as well, as mentioned by Wayfarer wherein ‘citizens are redefined as consumers’.
Elsewhere, the political philosopher William Connolly emphasises the commitment to the active maintenance of market mechanisms across all domains as a signature of neoliberalism: “Neoliberals... often do not think that markets are natural; they think markets are delicate mechanisms that require careful protection and nurturance by states and other organizations. The state does not manage markets much directly, except through monetary policy, but it takes a very active role in creating, maintaining, and protecting the preconditions of market self-regulation. The most ambitious supporters want the state to inject market processes into new zones through judicial or legislative action, focusing on such areas as academic admissions, schools, prisons, health care, rail service, postal service, retirement, and private military organizations” (Connolly, The Fragility of Things).
One thing to note about these definitions is that neoliberalism is thus not just a newer, shinier label for capitalism, which has more to do with widening the circuits of commodification (turning all sorts of life processes into commodities for the extraction of surplus value), rather than extending market metrics to non-market domains. It’s the difference between ‘how can we make money from this?’ and ‘how can we measure this with market-like metrics?’. As Brown notes, this latter question may have nothing at all to do with money: "Importantly, such economization may not always involve monetization. That is, we may think and act like contemporary market subjects where monetary wealth generation is not the immediate issue, for example, in approaching one's education, health, fitness, family life, or neighborhood. To speak of the relentless and ubiquitous economization of all features of life by neoliberalism is thus not to claim that neoliberalism literally marketizes all spheres, even as such marketization is certainly one important effect of neoliberalism. Rather, the point is that neoliberal rationality disseminates the model of the market to all domains and activities - even where money is not at issue.”
As far as these understandings of neoliberalism go, Agu’s strange association of it with sexual promiscuity and identity politics seems, at best, complete misunderstanding, and at worst, utter fantasy. If anything, as authors like Connolly (Capitalism and Christianity, American Style) and Melinda Cooper (Family Values: Between Neoliberalism and the new Social Conservatism) have shown, neoliberal positions tend to hew closely to social conservative positions (as can be found in the work of neoliberal scholars like Gary Becker, Richard Posner, and Milton Friedman, not to mention in the policy initiatives of those like Reagan, Thatcher, the Bushes, and even - perhaps especially - the Clintons; on this at least Agu is right - Clinton is a neoliberal shill who deserves everything she got). The idea however that Trump stands like anything close to a bulwark against neoliberalism is a position halfway between madness and fantasy, with a good dose of hilarity thrown in. That anyone could believe this - and say it with a straight face - is living in wonderland.
