Many people have old class narratives for why fascism is rising across the world, such as economic anxiety and others, narratives I have even promoted in the past, however me being a more 21st century intersectional feminist and a pro-tech leftist, I propose a different hypothesis.
I think what's going on is that the internet is a revolutionary technology that has accelerated social progress when it comes to the awareness of marginalized groups, such as queer people, alterhumans, plural systems and more.
It has also created a more global and interconnected world, to the point that authoritarian regimes have to censor the internet, because now any atrocity is now instantly known across the world, even when a US aligned country like Israel commits an atrocity it's no longer possible to hide it.
And I think because of all of the above, I think there's a global reactionary backlash to the accelerated social progress and interconnectedness the internet has created. As you will notice, the reactionary backlash exists regardless of ideology.
From fascist who I don't have to explain why are opposed to it, to transphobic liberals, to communist who see queer people as bourgeois decadence. essentially what's happening is all reactionary forces are uniting regardless of ideology to oppose the accelerated social progress and liberation of marginalized groups, or what these people call "wokeness."
in fact I'll go as far as say it's the reason why now the reactionary forces are trying to censor the internet with things like project 2025. Because they're so scared of the way the internet is creating an interconnected world, that they're afraid of the possibility of it taking away their power.
ultimately the 21st century will be the battle between ultimate progressivism and ultimate conservatism within the ruins of liberalism.
