Thanks Derek & Alessandra.
I agree with both of your points about empirical questions (and I don’t think you disagree).
The question of whether humans are sexually dimorphic with male and female types, and that males who say they are women are not in fact female, is one of basic science. This is unquestionably true.
But the question about what people think about words, and norms and who should be allowed in to which spaces is one where surveying public opinion (using clear words linked to concrete reality) would help. In the UK women who were concerned about the lack of empirical evidence on this crowd funded to commission a representative survey https://twitter.com/helenstaniland/status/1055128955894808577 — this is the source of my two graphs above. It was difficult even to find a survey company willing to ask the question in clear words understandable to ordinary people.
I wish the OGP had commissioned a similar survey with women in Côte d’Ivoire, Burkina Faso, Senegal, Kenya, Ghana, Indonesia, the Philippines, Uruguay, Costa Rica, Mexico, Morocco and Tunisia, to find out what they think, before it went ahead and redefined them as being people with an innate feminine identity, rather than female bodies.
