We have been told - as I interpret it - that we can only refer to the sex of a transperson if it is directly relevant to the post.
However, in the feminism section, surely the biology and socialisation of a person will always be relevant? Whether (to nick two examples) the post is about what sex someone providing intimate care is, or whether the post is about how someone behaved in the queue at Sainsbury's.
This is what is confusing me, and as far as I can see what is confusing other posters too.
