This has been called book banning for a very long time. Banned Books Week has existed since 1982.

I suspect that the same applies to most of the words that came to your mind; they're just being used in contexts you politically disagree with and therefore it's a "misuse". (Seinfeld's "soup nazi" was a misuse. Putin's use of the same word is a misuse. Descriptions of modern nationalist movements and the powers that support them are descriptive.)

There is a concept for pets called "banned breeds" (e.g., "pit bulls") that are similarly politically motivated in the same way that book banning happens.
