Just another attempt to erase the concept of biological sex, the idea that what was observed at birth might be wrong, not only for the vanishingly small percentage of infants with DSD whose sex cannot be easily visually observed.
This approach benefits transgender advocates, and it harms many others, particularly anyone trying to address sex-based oppression in this world. Why don't women and girls in Afghanistan just identify out of their oppression? If we can't even mention the reason for their oppression, we are not going to have effective feminism in the future.
