While I agree with your sentiment, it's more and more clear to me that reality doesn't reflect it. Many people are extremely easily influenced by easy to digest soundbites.
I'm often baffled by the level of superficial and binary thinking even in "intellectuals" (as in people who hold degrees and you'd expect to have at least a modicum of critical thinking). More often than not it seems based on emotions.
Now have these people spend most of their waking hours doomscrolling some echo chamber on tiktok, and I can see why some may be worried about the influence of some "bad actor".
Given this, and the highly polarized political scene (and I'm in Europe!), I have to say I'm quite worried as to how things will unfold. Hell, there's no need for Sergei and his friends! Just the local politicians' popularity contest is enough.
