In a way this perfectly captures my experiences too, despite my struggles revolving around a different topic, and sometimes it wouldn't even be algorithmically inflicted, but self-inflicted.
I'd keep coming across, and sometimes seeking out, threads with political content. But beyond that, I'd keep stumbling upon or even seeking out people who are being (in my view) inciteful or misleading. This would then piss me off, and I'd start to spiral. Naturally, these are not the kind of people who'd be posting in good faith, adding even more fuel to the fire when I engaged with them and their replies would eventually come about, which of course I'd "helpfully" get a notification for.
