Not necessarily behind all of it, they just learned to push the right buttons and tilt the scale. They just fuel wedges, disatisfactions, and divisions that already exist, they learned that amplifying them is making democracies ungovernable. So they keep doing it because, unfortunately, it's absurdly effective.
Only blaming Russia for all of it is just another way they win this propaganda/hybrid warfare, you don't take seriously the grievances of the "other side" because you feel it's all just fueled by Russia. It isn't, those grievances and problems are real, they've just been amplified and twisted, and by getting worn down of how much vitriol is spewed from whatever is the "other side" to you it works. It makes you emotionally tired and wanting to fight back by spewing your own vitriol, there's no more conversation, only stupid discourse, the division only grows from there.
