Dr. Seuss is actually a really interesting character to look at in history because he was super raciest, especially towards Japaneses, I mean it was WWII so especially anti-Japanese propaganda was every where and Dr. Seuss was paid, and wanted, to aid in that, and he also did some of it on his own accord. After visiting Japan and actually meeting these people he changed his views, like entirely. His next book was Horton hear's a who, which he dedicated to one of the friends he made in japan. Everyone likes to use Horton hears a who for a topic that has been band on here, but it was written as an apology, a correction of his previous works, "A persons a Person no matter how small" Is in response to racism. It's a correction of what he used to think.
I'm betting Seuss would understand why those books are no longer being published, and agree with the reasoning behind it if he were still around.
