“We need to respect the dignity of people who identify as transgender,” Anderson argued in the book, “but without encouraging children to undergo experimental transition treatments, and without trampling on the needs and interests of others.”

While the book was well-received by conservatives, LGBTQ activists have dismissed the book as anti-trans and “dangerous.”

“People who have actually read my book discovered that it was a thoughtful and accessible presentation of the state of the scientific, medical, philosophical and legal debates,” Anderson told Newsweek. “Yes, it advances an argument from a certain viewpoint. No, it didn’t get any facts wrong, and it didn’t engage in any name-calling.”

He argues that the book’s research is more important than ever before given the recent push for trans policies from the new Biden administration.

On his first day in office, President Joe Biden undid a host of Trump-era policies and issued a sweeping executive order, protecting gay and transgender people from discrimination in schools, the workplace, health care among other facets of daily life.

“Children should be able to learn without worrying about whether they will be denied access to the restroom, the locker room, or school sports,” Biden’s executive order stated. “Adults should be able to earn a living and pursue a vocation knowing that they will not be fired, demoted, or mistreated because of whom they go home to or because how they dress does not conform to sex-based stereotypes. People should be able to access health care and secure a roof over their heads without being subjected to sex discrimination.”

Days later, Biden also reversed former President Donald Trump’s ban on transgender individuals serving in the U.S. military.

The House of Representatives is expected to vote on the Equality Act this week after Democratic Representative David Cicilline of Rhode Island reintroduced the LGBTQ rights bill last week.

The Equality Act would prohibit discrimination based on sexual orientation and gender identity in employment, housing, credit, education, public spaces, public funding and jury service.

While it passed the House in 2019 after eight GOP lawmakers broke party ranks in a historic vote, the bill was stalled in the then-Republican-controlled Senate. But sponsors of the bill are hopeful that it could pass now that the Senate is split 50–50.

Anderson said that although his book has been praised by a number of psychology experts “none of that matters. It’s not about how you say it, it’s not about how rigorously you argue it, it’s not about how charitably you present it. It’s about whether you dissent from a new orthodoxy.”

However, it remains unclear as to why Anderson’s book has been removed by the online retailer.
