No, it's not "common knowledge" that abstaining from politics is siding with the oppressor. That's an unfalsifiable ideological assertion that has been well-socialized, but that doesn't make it fact and lots of people disagree with it, because it's an opinion, and it's one that presupposes a Foucaultian worldview of human dynamics as being able to be distilled down to pure power struggles. It's absurd to see that bandied about as truth just because it's "common knowledge." I bet in Communist China it was "common knowledge" right before the famine that killing the sparrows would bolster the harvest, too.
