Your response was to the 'Have you ever met a transwoman' failed 'gotcha'.
It highlights one of my big problems with the TRA arguments: they are so anecdotal. Now I enjoy a good anecdote as much as the next person, but when it comes to massive societal change - changing language, the law, education, medicine, building regs etc etc - I demand more than anecdotes.
There are non-anecdotal things like facts, statistics, a sense of proportion, justice, fairness, logic, common sense which should be much more important to policy-makers, education, legislators etc than the slew of anecdotes like
'I know two transwomen and they are lovely lovely people therefore sex is a spectrum, GC women are transphobes, JKR is the Devil Incarnate, and every building now needs a 'third' space which is only a 'third' space because we either can't count, or disabled people and their spaces don't count - but anyway that's irrelevant, my lovely lovely trans friends are sad and they are demanding 'third spaces' to make them happy, because they just want to pee, so -
What do we want? Third Spaces! When do we want them? Now. How do we propose financing and building them, and continuing to guarantee single sex facilities? Not our problem, bigots!
