In March 2019, Whitcoulls, one of New Zealand's leading book retailers, temporarily removed the book from their stores and online catalogue, apparently in reaction to the Christchurch mosque shootings. The withdrawal of the book was prompted by social media photos of Peterson posing with a fan wearing a T-shirt saying "I'm a proud Islamophobe." Peterson and his supporters strongly criticized Whitcoulls's decision because Whitcoulls continued to sell Adolf Hitler's "Mein Kampf" and Henry Malone's "Islam Unmasked". The book was reinstated six days after it was removed.
