So you admit it while spinning some story about how it's the opposite by claiming the right perceives books to be left wing propaganda? Got it!
Look, I'm all for not exposing kids to racist stereotypes if that's indeed what was happening with some suess books. Call it out, criticize it, but let people see for themselves and make the decision if it's actually racist and not let their kids read it.
Regardless, the real concern is illustrated by the examples in the article I linked.
The point of the meme however is that it's the left that wants to be authoritarian and ban books. It's really that simple.
