Pizza Hut is under fire from its customers who are calling for a boycott of the pizza chain over a book recommendation it recently made for its kids’ book club, which references a child that becomes a drag queen.

The book in question is “Big Wig” by author Jonathan Hillman and illustrated by Levi Hastings, which “celebrates the universal childhood experience of dressing up and the confidence that comes with putting on a costume,” according to the Book It! book club website.

The website continues to describe the book by saying, “And it goes further than that, acknowledging that sometimes dressing differently from what might be expected is how we become our truest and best selves.”

The book, which is targeted toward grades PreK to 3, has caused a firestorm on social media as customers of Pizza Hut have called out the chain for endorsing it for kids.

In a series of tweets, former Pizza Hut customers criticized the pizza maker by saying it had gone “woke.”

Others on Twitter said slammed the restaurant by saying, “It’s time to switch to Papa John’s” or they were only eating at “Little Caesars for now on.”

Still, others said it was time to boycott Pizza Hut, while others said they lost a customer over this decision.

Several people on Twitter said they were no longer going to buy pizza from Pizza Hut, saying they were going to avoid its restaurants from now on.

But many others supported the pizza company for recommending the “Big Wig” book.

The book “Big Wig” was published by Simon & Schuster in February. It is a story about a child who competes in drag in a neighborhood costume competition. Here, they become B.B. Bedazzle, and a wig is a key part of their ensemble that helps instill confidence and inspire dreams in those that also wear the wig, according to the author’s website.
