This attitude of “all politics and politicians are equally dirty” is straight out of the russian propaganda playbook. This is the narrative they’ve pushed in my country for decades, and it’s chillingly effective. It closely resembles whataboutism, whenever you criticize a politician, people yell “AS IF THE OTHER SIDE IS BETTER.”
Why push this narrative, you ask? So that people become so disillusioned and apathetic that they don’t vote, so it takes less votes for Russia to get the parties it wants into power. It also breeds internal dissent, malcontent, instability, leads to low voter turnout.
Russia also pushes a version of this at home, and in allies like Belarus. The gist being, all politics is dirty and corrupt, don’t get involved, don’t vote, nothing matters, it doesn’t concern you.
So yeah, sorry about the rant, but when i see variations of that quote “if your vote mattered, they’d make it illegal”, i get really annoyed. If your vote mattered, they’d make you think it doesn’t so you don’t vote.
