The difference between the US Guardian and the UK Guardian editors on trans rights is reflective of the difference between American and British Feminism at this moment in time.*
Feminism in the US seems to be (sometimes) moving towards an intersectional perspective that incorporates voices across the range on issues like class, race, and ecology.
British Feminism is extremely institutional, and is dominated by privileged women like Germaine Greer and JK Rowling.
