The political left has an urgent and rising problem with authoritarianism. An alarmingly high percentage of self-identified progressives are punitive, bullying, and intolerant of disagreement – and the problem is getting worse.Using his own cutting-edge research, leading psychologist Luke Conway shows that it’s not just right-wing extremists who long for an authority figure to crush their enemies, silence opponents and restore order; it’ s also those who preach ‘be kind’ and celebrate their ‘inclusivity.’ A persistent proportion of left-wingers demonstrate authoritarian tendencies, and they’re becoming more emboldened as they gain cultural and political power. On a range of scientific and social issues, they are increasingly advocating censorship over free debate, disregarding the rule of law, and dehumanising their opponents. These tendencies are part of an accelerating ‘threat circle’ of mutual hatred and fear between left and right that could tear apart our basic democratic norms.Concluding with an eloquent call for firm but rational resistance to this rising tide of liberal bullying, Conway presents a way forward for our hyper-partisan era.
