Also on the page: a man with a 10 foot beard, a magician, and a Chinese man. Only one is identified with his race, and is dressed up as a stereotype that was already out of date in 1950. It's also not the only racial stereotype in the book. We'll sidestep for now Seuss's use of racial caricatures during wartime propaganda. Listen, I'm not Chinese, and I can't tell you to be offended, but I can certainly look at it and empathize with the people who do find it offensive.
As for the second question, that's a question for Dr. Seuss Enterprises; they made this decision about the works in their custody.
You may think you are helping by supporting these moves and empathizing with those who are offended, but I truly believe it has the opposite effect. Is it really worth saving some thin skinned people from offense if it pisses off enough people that the entire system becomes destabilized? Because that's exactly what's happening.
