I can tell you right now, Verbeena, I will never refer to Karen White, Davina Ayrton, Lisa Hauxwell, Clare Derbyshire, etc. etc. as "She." I will not do it.
Coming down a notch or two from convicted rapists and murderers, nor will I refer to people cheating their way to medals in women's sports as "she." I will not do it.
I will play "let's pretend" with trans-identifying people I know and like, in the same way that I address Christmas cards to my friend who is a vicar as "Reverend so and so". But that's a courtesy I extend to people I like, not a rule which I will allow to be imposed upon me.
