Gender Queer is 18+ and Not All Boys Are Blue says 15+ on Amazon, so yeah, either adults or high school and up. They love to act like evil librarians are trying to give 2nd graders pornography, though.
They don't even want high schoolers to read that stuff. Not like they couldn't get it other places or that generally by high school kids have a grasp on their sexuality or are figuring it out. And books like that can really help kids who are in a tough spot, like being lgbtq+ and having an asshole like Kennedy here as a father.
Even Gender Queer isn’t that bad. It’s got a single frame of objectionable material. I would say that something like Watchman has much more objectionable material, but nobody is clamoring for removing that from libraries.
I disagree. Gender Queer talks about going to websites like kink.com to explore sexuality. That’s not high school material. That site is hardcore BSDM.
