Great contribution.

The sad thing is that while this is only a conversation on the internet, there are people out there passing laws affecting actual humans with the same amount of actual exposure to those humans and based entirely on their own imagined discomfort.

What if I asked to be addressed as "Sir"? Would it matter if I were nobility, or a nobody just trying to assert dominance? Or if you hated me and thought I was the opposite of a gentleman? But what if I thought of myself as a perfect gentlemen? Are you bound by my self perception?

Ridiculous is a relative term. If I think a request is ridiculous, am I free to ignore it?

It may indeed be. I likely don't have the time or energy to correctly address people who insist on being called they/them, or xe/xem. I have enough trouble remembering people's names.

Or would it be an implicit acceptance of the presumptions implied?

Would that not matter since it's their identity?

Forget nicknames, how would these people feel if somebody just said "Hey I'm going to call you Arnold now, because you fit my mental image of Arnold." Wildly inappropriate thing to do?

If you want to go and impose whatever pronoun you want on someone based on how they look, don't act shocked when you get called out for being a dick to them.

I've not seen someone suffer negative consequences for calling someone else the wrong real name. I've seen instances of negative consequences for someone using the wrong pronoun though.

Or is it because deliberately going out of your way to call people the wrong name to make a political point isn't a thing that anyone does, so nobody has needed a rule to make them knock it off?

You know, in being subtle like that, I fear you might not be making your point clearly enough for the others.
