There have been numerous studies over the years into the mentality of Rightwingers, identifying their salient characteristics, such as egotism, relative lack of empathy and compassion, paranoia, the drive to control others and their indifference to the fate of others, ready recourse to violence to get their way and their insatiable greed. The psychology, in short, of the psychopath.
Of course these characteristics follow a continuum, with the more florid specimens at the end of outright fascism and brutal authoritarianism, right back down to those with many fine features who identify as 'Rightwing' out of allegiance to family or some other group in which they were socialised. It is, however, indisputable that they Right dominates the planet, has done so throughout recorded history, and they are becoming more extreme by the day.
As each new Rightwing regime here, or in the UK, or the other Anglosphere countries and throughout the EU, reveals itself (after lying assiduously in order to get elected) to be fanatically Rightwing, launching ever more vicious attacks on working people, privatising everything that can be privatised, deliberately increasing inequality and poverty, driving down wages and stripping away conditions, one target gets special attention. And that is environmentalism, the Right's pet hate for decades. Environmental legislation is being wound back decades, with advances made by Communist 'water-melons' like Richard Nixon and Rupert Hamer gutted, and the science of anthropogenic climate destabilisation, in particular, treated with utter animosity.
The reason why is plain. The neoplastic system of capitalism, created by the Right over centuries, and which promotes their type to the detriment of the rest of humanity, is antithetical to the idea of environmental stability and sustainability. Capitalism must grow, like a cancer, or die. In the process it will, like the cancer, kill its host, humanity. So as long as the Right and their operating system, capitalism, prevail, human destruction is certain. Unless we remove the Rightwing authoritarian personality type from its position of absolute global dominance, and replace capitalism with a system that ensures human survival, we will disappear in a cataclysm of rapid climate destabilisation, and the consequent famines, epidemics and wars, certain to end up nuclear. It's really a simple choice-Them or Us, the Right or humanity.
