Surely the answer is "Depends which bit of it you're quoting." For example, if you quote something that calls for genocide then, obviously, yes. But if you were to quote something relatively innocuous, then yes because you're quoting from a book that, among other things, calls for genocide.
For example, if you quote something that calls for genocide then, obviously, yes.
I disagree. If you quote it in a manner that encourages genocide, then yes, absolutely. But if you properly contextualize the quote, there is no such possible quotation that should be outright banned. Context matters, and intent matters. It's important to be able to discuss difficult subjects in a respectful manner, and sometimes that requires verbatim reproduction of hateful artifacts of speech.
