"perfect language swap"

Where does right-wing extremism come from, and why are so many ostensibly "liberal" people falling for it?  George Monbiot takes a stab:

"I believe this synthesis of left-alternative and rightwing cultures has been accelerated by despondency, confusion and betrayal. After left-ish political parties fell into line with corporate power, the right seized the language they had abandoned. Steve Bannon and Dominic Cummings brilliantly repurposed the leftwing themes of resisting elite power and regaining control of our lives. Now there has been an almost perfect language swap. Parties that once belonged on the left talk about security and stability while those on the right talk of liberation and revolt.

But I suspect it also has something to do with the issues we now face. A justified suspicion about the self-interest of big pharma clashes with the need for mass vaccination. The lockdowns and other measures required to prevent Covid-19 spreading are policies which, in other circumstances, would rightly be seen as coercive political control. Curtailing the pandemic, climate breakdown and the collapse of biodiversity means powerful agreements struck between governments – which can be hard to swallow for movements that have long fought multilateral power while emphasising the local and the homespun."
