Or maybe a broken political and economic system is causing a gathering of wealth in the hands of the 1% which is a major factor behind both climate change and increasing authoritarianism

I have had the belief for a few years that the rise of fascism is an emotional response to being afraid of an uncertain future that people feel like they have no power over.

It was 9/11 butterfly effect. The US’s wars caused a refugee crisis, xenophobes across North America and Europe got their panties in a bunch about all the new brown people, turned to nationalism. New (and popular) authoritarian anti terrorism laws probably didn’t help either.
