Here are several questions for biologists and medical professionals: If a person is found to have XY chromosomes (heterogametic sex), does a designation as female on his birth certificate, driver's license or Social Security card override the chromosomal evidence? Similarly, if a person is found to have XX chromosomes (homogametic) does a designation as male on her birth certificate, driver's license or Social Security card override the chromosomal evidence? If you were a medical professional, would you consider it malpractice for an obstetrics/gynecology medical specialist, not to order routine Pap smears to screen for cervical cancer for a patient who identifies as a female but has XY chromosomes?
If you were a judge, would you sentence a criminal, who identifies as a female but has XY chromosomes, to a women's prison? A judge just might do so. Judge William Pryor of the U.S. Court of Appeals for the Eleventh Circuit focused on a Florida school district ruling that a transgender "boy," a person with XX chromosomes, could not be barred from the boys' restroom. Pryor suggested students shouldn't be separated by gender at all.
Fear may explain why biologists in academia do not speak out to say that one's sex is not optional. Since the LGBTQ community is a political force on many college campuses, biologists probably fear retaliation from diversity-blinded administrators. It's not just academics and judges who now see sex as optional. Federal, state and local governments are ignoring biology and permitting people to make their sex optional on one's birth certificate, passport, Social Security card and driver's license. In New York City, intentional or repeated refusal to use an individual's preferred name, pronoun or title is a violation of the New York City Human Rights Law. If I said that my preferred title was "Your Majesty," I wonder whether the New York City Commission on Human Rights would prosecute people who repeatedly refused to use my preferred title.
