I think it helps to have a bit more background of quite what we are dealing with here

And the reasons Posie has ended up with the action of the billboard (which was what she was invited to discuss..the billboard, why it happened and the behaviour of transactivists, not India Willougby).. As women are just not being listened to. This has forced the issue really, and oddly enough, most people appear to agree with Posie, though seem to think she has a very harsh way of putting her opinions across. But yes, noone actually thinks transwomen are women. Hence 'transwoman'. And thats ****ing fine! Except apparently its not.
