It’s not the first time Amazon has heard from book authors over negative customer reviews. In 2012, Anne Rice and other famous authors signed a petition that called on Amazon to remove anonymity from its reviewers to prevent “bullying and harassment.”

Anderson, the William E. Simon senior research fellow at The Heritage Foundation, welcomed the news.

“The future of marriage and religious freedom is a subject of a fair bit of disagreement,” he told The Daily Signal. “It’s important that we carry out this debate with civility and grace. That’s exactly what I tried to do in my new book.”

His book, which has 3.8 out of 5 stars in ratings, comes out in paperback in August.
