Curate, connect, and discover
All-in-all, reading has a lot of benefits and by limiting the diversity of books, you are taking away some of these benefits and taking them entirely from someone who might have started reading if they had just read *that book*. Earlier today the Washington Post listed other reasons to not fall into the paranoia of banning or challenging books from the superficial: a lot of classic books were at one time banned; many books are based on issues with unique diversity and representation that are unique in a society becoming more accepting (in most places), and when you find a book has been banned or challenged, that may start a conversation.
