There seems to really be a push currently to, "Ban," books/comics/etc. from libraries or being taught in schools. If you're that upset about your children or even other adults learning about race, LGBTQ+ subjects, or simply questioning your family's beliefs, then maybe you need to take a long look in the mirror about why the things you hold so dear could crumble like a house of cards if people read a book questioning what you think.
Throughout history the people who tried to ban or burn books were the bad guys, so look at the side where you currently are choosing to stand and think about what it means. It isn't about protecting people from, "Explicit materials," or, "Questionable views." It is about preventing anyone from learning an alternative to what you believe is true. Again, if you're that worried exposure to other views will, "Harm," children or adults, who hold a different view, maybe that belief needs to be challenged even more.
