They do not promote anarchy, they promote totalitarian rule. Put all those 'climate change deniers' in prison, force them to eat bugs instead of meat, deny them any human rights, that kind of thing.

So when you say a "threat to rule of law" you mean too much law? That seems confusingly worded.

Once people are sufficiently radicalised, laws are not required anymore to put an “enemy” in prison (or worse).

For most young Westerners who have never known anything but rule of law, that’s probably difficult to imagine.

literally no one with power has seriously proposed anything like this — quite the opposite in fact, the previous US president suggested that windmills cause cancer

Forgive me for interrupting your attempts to refute the "Liberal Fascism" trolling...

One scenario I've heard, and has me a bit worried, is climate crisis begets a right wing reactionary environmentalism. Basically all the same nativist, anti-immigration, isolationist, anti-trade, yadda yadda, but with an "environmental" justification.

So instead of mitigating or undoing the damage, the reactionaries would be energized by protecting what we have from "the other".

Not too hard to imagine a crackdown, if scarcity leads to hunger leads to unrest.
