Nonsense. 100% nonsense. To the contrary, acting like only one side is bad and thus only one side can be made fun of is a huge reason we're in this situation. The right took the left's cancel culture and weaponized it to the extreme.
South Park's "all sacred cows slaughtered equally" doctrine is a huge part of what kept them interesting, refreshing, and relevant for so long. Their descent into hyper-focus on Trump and his regime are a big step backwards.
I say this as someone who thinks the current situation is catastrophically bad for America, by the way. I'm not minimizing Trump's disaster.
As someone who is very bought into the mindset that all systems of people do stupid, short-sighted, and occasionally outright evil things, and yet thinks that maybe they're better than the alternative of burning everything down, I do not agree that MAGA is the only thing that makes sense.
