Dr. Seuss hated the Japanese via orpheus.ucsd.edu

“Perhaps it is no surprise that American cartoonists during the Pacific War painted Japan in overtly racist ways. However, it is a surprise that a person (Dr. Seuss) who denounces anti-black racism and anti-Semitism so eloquently can be oblivious of his own racist treatment of Japanese and Japanese Americans. And to find such cartoons - largely unreproached - in the pages of the leading left newspaper of New York City and to realize that the cartoonist is the same Dr. Seuss we celebrate today for his imagination and tolerance and breadth of vision: this is a sobering experience.”
