Yeah! And for that matter, has Jon Stewart atoned for his sin of leaving The Daily Show in 2015? If he had stayed, no way Trump could have won! And why didn't Oprah run in 2024--she could have saved us! It's all their fault!
Get real.
I don't think South Park ever implied both parties are equally bad. Just that they are both bad. And I don't think irreverent satire is prep work or psy-op propaganda for an authoritarian government. If anything, it's the inoculation.
It's quite clear that you haven't watched the series in the past decade. I'm sure you wouldn't be crowing the same tune if you'd watched the Mr. Garrison storyline.
I watched the first 13 seasons of South Park as they aired and the post you're replying to feels like at least a sincere and reasonable interpretation of SP's politics.
What season is the Mr. Garrison storyline from?
Why is it insufficient to (assuming the poster isn't lying to us) watch SP for 20 years before drawing a conclusion about it and the creators? They owned up to not having watched recently before asking about whether things have changed. I don't understand the weird hostility in your post when they owned up to the limitations of their PoV.
