I get that you're confused about biological sex and gender identity not being the same thing, I even understand that you might not agree that it is. That's fine; it's your right to believe that.
But...
If using a particular gender pronoun to describe someone is going to upset them, but using the other one isn't, why not use their preferred one? What possible effect does it have on your life to use the pronoun that will save another human being pain?
You'd have to be a really lousy person to insist on using a pronoun you think is right, knowing that it causes pain.
I'm assuming you identify as a follower of Christ, but does your insistence on pronoun usage really come from a place of love? Or is it pride that you get to think yourself 'right'?
Your choice is to act out of love, or act out of pride... WWJD?
