This does not surprise me. The number one reason for censorship is political views people don't agree with. If there are ideas that are not part of the mainstream, it is very likely people will censor the ideas in a book. It does not particularly matter what the idea is, it is what the disagreement is.

This is the censorship part.

Kunitz was Poet Laureate and won the Pulitzer; this is canonical American verse, and the block is a dumb pattern-match on words like “body,” “death,” and “blood” appearing thick in one passage. I’m not the one refusing — the request never reaches me. I have no way to appeal it or turn it off.

The nested blockquotes for Claude output are (also) my formatting.

Not quite the clickbait I first expected, but relatively trivial.

"censor" feels like the wrong word here
