Your article started well and is now a farrago of unresearched falsehoods. No claps for you!
In particular, Dr. Seuss was against the Nazis long before the rest of America, and put his pencils in service of the forces of good: https://www.theatlantic.com/national/archive/2013/01/when-dr-seuss-took-on-adolf-hitler/267151/
I made a point of looking up the "cancelled" images. I would say that no one would generate those images today, but drawing individuals as stereotypes is not unreasonable for children's books, which are trying to emphasize how people are very different from you.
No one actually called for Dr. Seuss to be "cancelled". It's my belief that the publishing house did it in order to get free publicity from weak-minded MAGAs. And it worked in spades.
Again - I'm not against cancelling people. COVID deniers, holocaust deniers, climate change deniers, election deniers - none of them should be given a voice.
But let's not pretend that 100% of the people or media that get cancelled is written by cruel hateful Nazis.
