So there's no trans-women where you live then.
That's entirely different.
I said nothing about addressing anyone, only that you two and your misplaced taunts concerning his understanding of biology were wrong. If anything, you two apparently don't understand biology whilst he does. Compared to the kinds of things he normally writes in this thread that are entirely subjective and come across like an entitled twit whining about not getting enough Ophelia time, you've made him seem like the rational and level-headed out of the three of you. Congratulations.
We're not obliged to address a trans-woman as "she", any more than as "he", and vice-versa for a trans-man It's our choice to address them as either, but calling a trans-woman a man/addressing one as "he" is not wrong in a factual/accuracy sense of the word.
