At Public we learn that many anthropologists consider it impolite to acknowledge that there are two sexes. An excerpt:

In the field of anthropology, it’s difficult to avoid talking about sex. For physical anthropologists, much of the field’s focus is on skeletal remains where body size, bone mineral density, and other sex differences are of utmost importance. For forensic anthropologists, determining the sex of remains is a crucial element of identifying crime victims. Archaeologists, too, glean valuable insights into social structures by studying "grave goods" interred alongside individuals of each sex.

Thus, the distinction between males and females is crucial in the study of human beings and their cultures. So when a group of anthropologists organized a panel titled, ‘Let’s Talk About Sex, Baby: Why biological sex remains a necessary analytic category in anthropology,’ for the 2023 American Anthropological Association (AAA)/Canadian Anthropology Society (CASCA) conference, the only reasonable question that should arise is why this seemingly evident truth even needs stating at all.

However, we are not living in reasonable times. Despite having their panel approved by both the AAA and CASCA in July, a little over a month before the event, the panelists received notice that their session had been removed from the conference program. The rationale behind this decision was that the ideas to be discussed would "cause harm to members represented by the Trans and LGBTQI of the anthropological community as well as the community at large." What’s more, the AAA explained that the decision to cancel the session about one of the most fundamental aspects of human existence was reached in the spirit of respect for the values of the AAA, the “safety and dignity of its members, and the scientific integrity” of the program.
