Gender ideology has caused enormous confusion in the courts of many countries. Several years ago, I was invited to give a lecture on the topic at a Polish scientific conference. If you would like to read the talk, titled “Transsexualism as Transhumanism,” you can find the English version here and the Polish version here, or you can just go to the Articles page.
The conference was “Adjudications of Courts in Cases Relating the Sexual and Gender Minority vs. Human Good.” The sponsor was The Institute of Justice in Warsaw. All of the conference papers have been published in a book, edited by Przemysław Ostojski and Mark Regnerus, which I recommend to anyone who wants to dig in: Contemporary Problems of Protection of Marriage and Identity of the Person in the Light of American and European Case Law: An Interdisciplinary Approach.
