Kay frequently writes anti-trans texts, including her co-authored book on trans women in sports. In reply to quoting a neo-Nazi to legitimize her anti-trans statements, she said: "“With regard to the application of the quote to the Church of Gender Identity,” she tells CANADALAND in an email, “I do not regret it at all, and here is why. The quotation makes a great deal of sense. The fact that an anti-Semitic conspiracy theorist actually believed that the Jews ‘rule over you’ says a great deal about his twisted mind, but it does not reflect reality. I am neither a conspiracy theorist or a transphobic. My quarrel is not with trans gender people, who — I have said this repeatedly — simply want to live their lives in peace, but with the ideologues who are bent on imposing their belief system, founded in theory, but not in evidence, on everyone in the form of compelled speech and compelled expression of belief.”
