Q.  If someone asks you to use a pronoun for them other than the normal ones, what is your response?
 
A.  I use them.

Just as I use whatever name they tell me is their name.  I don’t ask to check anyone’s driver’s licenses or birth certificates to make sure that the name they’re asking me to use matches whatever name somebody official said was theirs.

I just call people what they want to be called.  Because it’s fucking polite.
