I don't think there's any weird forces, I just think that if you don't look after something, it deteriorates. Whether that's a house plant, your car or....democracy.
We all of us have taken democracy for granted too long and forgotten how special and unusual it is, so it's degraded.
I suppose there are 'forces' like China which I absolutely believe uses Tik Tok to enforce mental illness and vulnerability in our youth. And I am sure there are state actors messing with social media in general, to turn us against each other and make us divided and angry, which they have succeeded in doing.
But the best efforts of rival empires would fail if we had curated and cared for our democracies properly, which we haven't.
So it's mostly our fault. Mostly my generation and the one above me, not millennials and gen z.
