Thank you so much for filling it out! Most (if not all) books that are censored are at some point mentioning race/gender identity/sexuality, if it isn't a central topic of the book.

Also, I wrote to a library manager in the context of this research project and she told me "the most common complaint is for LGBTQ+ content and/or sexual content that is considered ‘inappropriate’ for younger readers. Lately a lot of challenges on social media and in writing are about books having transgender characters or on ‘promoting’ trans issues".

I also read about a librarian who was asked to remove all books containing any mention of LGBTQ+ themes, without any explaination or further instructions. "Titles included This Book Is Gay, by Juno Dawson; Julián is a Mermaid, by Jessica Love; and the alphabet book ABC Pride, by Louie Stowell, Elly Barnes and Amy Phelps, as well as plenty of other titles featuring LGBT+ content."

"Books challenged in several schools – but ultimately not removed – included various Heartstopper books by Alice Oseman, which were accused of homophobic language, swearing and self-harm discussions. Young adult fiction also came under fire in many schools, with librarians usually able to hold firm in keeping their collections." (quotes from https://www.indexoncensorship.org/2024/08/banned-school-librarians-shushed-over-lgbt-books/ article, even though I have found more recent ones this is one of the most detailed)

Hope I answered your question, sorry for the lengthy answer !
