Here is the true message of this special since both the left and the right are too stupid to understand:
Pandering is a lazy form of storytelling, but sending hate to Disney doesn't solve anything. If anything, it gives them a reason to do more pandering. Cartman is DEFINETLY NOT the voice of reason of this special. Stan and Kyle are. Their cordial speech on why pandering doesn't work is Trey and Matt's voice being heard. Stuff like Miles Morales is a great way of representation because it is innovative and a complete new spin on a classic character. Race swapping is just lazy.
I hate how the left wing only focus on the part where Cartman says "complaining about woke stuff is kinda lame" at the end, and use it as the basis of what they think the message of the special is, as if it is in favour of their side only. Disliking pandering isn't a right wing viewpoint, and I hate how people think it is. They missed the point.
I also hate how the right wing think that Cartman IS the voice of reason, thinking that the whole episode supports the their side only and that sending hate to Disney is the right way to go about it. It is annoying to see conservatives act like the whole episode is for them. They have also missed the point.
If people saw Star Wars (the series that arguably kicked off the hate mail) and just said CALMLY, "Idk, didn't feel the same. I didn't care for it."
This probably would have blown over. But the demonizing from one side lead to the other side doubling down
