Hate speech threatens our humanity

DO POLITICIANS’ words matter? Since becoming US President, Donald J Trump has dismissed his opponents and others he does not like as evil, stupid or both. He has referred to undocumented immigrants as animals, and to poor countries as shitholes.
Around the world, such harsh words have become normalized as part of the rhetoric of leaders, against perceived and manufactured enemies, to mobilize the intended ‘imagined community’ against ‘the other’.
Such rhetoric, increasingly emulated by political, religious and community leaders the world over, has contributed greatly to the growing climate of resentment and hatred of the ‘other’, the ‘outsider’, the ‘stranger’.
Fostering a culture of hate
Hate words and speech have become widespread globally. They have become part of dominant cultures, spreading meanings, worldviews and beliefs, all with considerable impact. When dominant, they are amplified by authority and power – political, economic, social, and cultural, increasingly recognised as ‘soft’ power.
The rhetoric of hatred has been echoed and thus amplified by traditional as well as social media, including the increasingly vicious culture online, as rivals compete to outdo one another, vying for attention.
But often, even more aggressive and vicious is the hate rhetoric of the rising cultural populists, as they manufacture new language to outdo one another and the incumbents, while trying to unify their ‘imagined communities’ behind them.
Cultural populism for imagined communities
Ethno-populists, jingoist nationalists, other chauvinists and their enablers try to convince their followers that they are victims facing threats from exaggerated or even imagined dangers, such as conspiracies by enemy ‘others’ of which they are ignorant due to obfuscation by fake news.
Around the world, they use cultural ignorance, unfamiliarity, suspicions, prejudices, animosity and fear-mongering to mobilize their followings, typically with ‘half-truths’, rather than less credible, outright fabrications.
In the era of fake news, fake alerts and ‘post-truth’, such half-truths have become more effective, and hence, more dangerous in abetting the power to demean, displace and destroy, especially when driven by ambition seeking greater influence and power.
The recent popularity, mainstreaming and legitimization of ethno-populism and jingoism in the West as well as other parts of the world, demand attention to how cultural analysis, social psychology and neuroscience can help us better understand the effects of such rhetoric.
Unsurprisingly, continuous or frequent exposure to hate speech is known to increase prejudice, resentment and animosity. Such influences desensitize people to verbal and even other forms of aggression, by ‘normalizing’ actions and behaviour which might otherwise be socially condemned. The culture of hate seems to thrive in the human ‘ecosystem’.
Leaders inspiring prejudice, anger and fear among their supporters, stimulate surges of stress hormones, such as norepinephrine and cortisol, affecting the amygdala, the brain centre for threat. Threatening language directly stimulates the amygdala, making it difficult for humans to ‘wind down’ their passions and emotions in order to ‘think’ before acting.
One does not have to be mentally defective or unstable to be ‘inspired’ to aggression and violence by such rhetoric. Most of us are susceptible to such ‘motivational’ speeches, especially when conditions are conducive.
Legitimizing violence against others
A study, led by Princeton psychologist Susan Fiske, has linked anger and violent impulses to distrust of ‘outsiders’ or ‘others’, especially when economic difficulties encourage viewing them as competing ‘unfairly’ for better opportunities.
By inducing or exaggerating a sense of external threat by the ‘other’, they can be thought of as not only different, but even as threatening. It is generally easier to think of outsiders as less than human, and hence, undeserving of empathy or compassion; both are cultural and socio-psychological conditions conducive to hate, aggression and violence.
A Harvard psychologist co-author of the study reportedly noted, “when a group is put on the defensive and made to feel threatened, they begin to believe that anything, including violence, is justified.”
Dehumanizing others
Cultural chauvinists also encourage antagonism to and violence against others by demonizing and dehumanizing them as sub-human or even non-human, so that they are not deemed worthy of treatment and consideration as fellow humans.
Earlier, Fiske and a colleague had found that their study subjects were so unempathetic to images of drug addicts and the homeless that they could not imagine how they felt or thought; the brain regions required to empathize with them as human beings deserving of ‘moral treatment’ could not be activated.
Instead, the brain region associated with feelings of disgust were activated. As Fiske has argued, “Both science and history suggest that people will nurture and act on their prejudices in the worst ways when these people are put under stress, pressured by peers, or receive approval from authority figures to do so.”
