I read some / skipped through Gender Queer and didn't find anything objectionable.
However, it's a book about someone's experiences being gender queer. For example, there's a part where the person finds Tumblr / etc communities where people list pronouns, and the author talks about how it made them think differently.
There's also a part where the person buys panties and gives the colorful ones to their friend Phoebe, then keeps the others for themselves.
A) Communities of like-minded people exist
B) Here are some ways I dealt with dysphoria (aka some ways you can deal with it.)
Two things much worse than nude art or talk about genitalia.
You don't need to be a brainwashing savant to understand these books are dangerous to conservative thinking
