You see, this is the problem, this is why the article exists.
People catch one episode of south park making fun of what they believe and sudenly south park is "Alt right" (ie, the enemy).
That episode had the message of "Fuck guys, if religion wants to survive in the modern world it has to get their shit together and evolve with the world", they also slightly made fun of atheist, but, man, south park's bread and butter is mocking religion mercilessly, south park makes a couple of episodes also making fun of atheists and suddenly it's "fuck this right wing shit?"
That's the part that seems disingenuous for me, South park has a lot to be criticised for but most people go full "they made fun of me, they're the Republican/conservatives/alt right/the enemy now!"
