There is now enacted or pending legislation in more than 30 U.S. states prohibiting certain kinds of books from being in schools – mostly LGBTQIA+ titles and books that engage with the presence of racism in our country. Because Scholastic Book Fairs are invited into schools, where books can be purchased by kids on their own, these laws create an almost impossible dilemma: back away from these titles or risk making teachers, librarians, and volunteers vulnerable to being fired, sued, or prosecuted.
To continue offering these books, as well as even more high interest titles, we created an additional collection called Share Every Story, Celebrate Every Voice for our U.S. elementary school fairs. We cannot make a decision for our school partners around what risks they are willing to take, based on the state and local laws that apply to their district, so these topics and this collection have been part of many planning calls that happen in advance of shipping a fair.
If your kids have read (or you have read to them) some banned books, and agree the reasons they're banned are wrong, you can buy the shirts, with the caveat that they can only wear them when you're there to protect them against anyone who reacts with violence. And if they're old enough to have their own battles with society, maybe you could get yourself a shirt which supports that cause.
