Late and tired to the debate on this thread, which seems to have veered, as usual, of original starting point
But if we're having to debate others here on whether people qualify for a sex category on whether or not they've had bits removed/weren't there in the first place, despite owning other indicators that you belong to that sex category (apart from an ephemeral 'feeling') how on earth can you have any sex category?
And if there's no sex segregated spaces and services because you can't define any category....that means there's no specific categories for people to 'transition' into to.
Somehow, I suspect the people fighting hardest to enter other people's spaces wouldn't like this very much. Just one 'human blob space' wouldn't make them happy! Would probably frustrate them! as every, every post highlights how much they want to enter other people's spaces, regardless of safety, dignity, other people's comfort.
"No,sorry, you have no special status, we're all just human blobs"
(This is lighthearted - as always there are spaces and rights some human blobs, who are female, need separate from other human blobs, male, because of history, biology, etc. The reasons for which are in no way lighthearted, sadly).
