Is this actually a big issue in books? I know the topic of forced diversity pops up in discussions of TV adaptions of books, like House of the Dragon, but I haven't heard people complain much about it when it comes to the books themselves.

I mean, I've never heard anyone say something like, Lord of the Rings could have been a decent book, but it just really needed more black, gay dwarves.

OP, which books are you talking about in particular?
