*For example, in And To Think That I Saw It On Mulberry Street, a character described as Chinese has two lines for eyes, carries chopsticks and a bowl of rice, and wears traditional Japanese-style shoes.
Another title, If I Ran the Zoo, depicts two men from Africa as shirtless, shoeless and wearing grass skirts as they carry an exotic animal.*
This is not, IMO, appropriate for the 2020's, and I have no problem with images like this being withdrawn, or just altered to make them more sensitive.
I don't see it as 'cancel' culture at all (that is far more invidious, I think), but more on the lines of no longer playing with golly dolls.
