When Harry Became Sally, Responding to the Transgender Moment, by Ryan T. Anderson (2018)

A detailed, thoroughly researched analysis of the ideas underlying the transgender phenomenon. Dr. Anderson argues that the best biology, psychology, and philosophy support an understanding of sex as a bodily reality, and of gender as a social manifestation of bodily sex. He explains how biology isn’t bigotry. He uses science and logic to critique the foundational principles of transgender activists.
