I understand it's hard for you to use different pronouns, but it's probably much harder for the person who feels like they don't identify with their gender assigned at birth.
> Requiring me to call someone who was born with a penis, and who has sired children a "she" is telling me to say that 2 + 2 = 5.
It's more like someone telling you to call them John and you call them Tyler instead. It's literally just a word.
