From Elizabeth Weiss, Anthropology Professor:

September 25, 2023, my fellow panelists and I received a letter from the American Anthropological Association (AAA) and the Canadian Anthropology Society (CASCA) informing us that our conference panel, “Let’s Talk About Sex, Baby: Why biological sex remains a necessary analytic category in anthropology”, which had been accepted, is being removed from the program due to the “harm” it will cause the “Trans and LGBTQI community”. We’ve responded to their accusation.

Here is the excuse for the cancellation for the organizers:

Dear panelists,
We write to inform you that at the request of numerous members the respective executive boards of AAA and CASCA reviewed the panel submission “Let’s Talk about Sex Baby: Why biological sex remains a necessary analytic category in anthropology” and reached a decision to remove the session from the AAA/CASCA 2023 conference program(me). This decision was based on extensive consultation and was reached in the spirit of
respect for our values, the safety and dignity of our members, and the scientific integrity of the program(me).

The reason the session deserved further scrutiny was that the ideas were advanced in such a way as to cause harm to members represented by the Trans and LGBTQI of the anthropological community as well as the community at large. While there were those who disagree with this decision, we would hope they know their voice was heard and was very much a part of the conversation. It is our hope that we continue to work together so that we become stronger and more unified within each of our associations. Going forward, we will undertake a major review of the processes associated with vetting sessions at our annual meetings and will include our leadership in that discussion

Here is an excerpt from the response from the cancelled panelists.

Your suggestion that our panel would somehow compromise “…the scientific integrity of the programme” seems to us particularly egregious, as the decision to anathematize our panel looks very much like an anti-science response to a politicized lobbying campaign. Had our panel been allowed to go forward, we can assure you that lively contestation would have been welcomed by the panelists and may even have occurred between us, as our own political commitments are diverse. Instead, your letter expresses the alarming hope that the AAA and CASCA will become “more unified within each of our associations” to avoid future debates. Most disturbingly, following other organizations, such as the Society for American Archaeology, the AAA and CASCA have promised that “Going forward, we will undertake a major review of the processes associated with vetting sessions at our annual meetings and will include our leadership in that discussion.” Anthropologists around the world will quite rightly find chilling this declaration of war on dissent and on scholarly controversy. It is a profound betrayal of the AAA’s principle of “advancing human understanding and applying this understanding to the world’s most pressing problems”.
