The difference here, and I am glad to point it out to you so you may never in ignorance make such a mistake again:
To afford a title of fealty is not the same as to afford a title you afford half of anyone, and which owes no fealty. I will have no gods or kings, and will not suffer any to live over me. Period. Should a king try to rule me I will kill them with all to my left and right who would seek such freedom.
So if you declare yourself as God emperor, I most certainly will treat you as I would any who would seek that title: not with my staff, but with my sword. And I do not think you would like to see a wizard make a sword.
Does that answer your question?
Very well, then.
As the rightful God-Emperor of Humanity, I hereby release you and anyone with whom you have ever interacted with or will ever interact with from any obligation of fealty to me, retroactively if necessary, unless they explicitly, of their own free will, and without coersion, pledge themselves as such.
You are all freemen as far as I am concerned.
All I ask is that you acknowledge and respect my stated gender (male human of superior genetics, intellect, and refinement) and my stated pronouns (M'lord/M'lord's) to the extent that you would do so for anyone else's declared gender identity. I ask this not as a god or a king, but merely as a person who has a monopoly on how I should be perceived and acknowledged, as do all people. Do you have any objections to doing so?
Edit: I related this latest interaction to my husband. While I imagine you are fine with me not treating you as I believe befits a god-emperor, he is absolutely extatic at the idea. He agrees to in fact use the full title as your entirety of pronoun.
If he wishes to re-pledge fealty to me, I have no objections to him doing so.
When I am not sure what to call somebody, I just use "they." In fact, I sometimes use "they" even if I do know somebody's gender identity. I honestly might into the habit of using it with everybody.
I did that with metaphor for a while. A rather large tantrum was thrown, and I will generally now afford more use of masculine pronouns as the need may arise.
Sometimes I admit it is a little bit enjoyable to not have to make mention of gender through the use of pronouns, nor address it at all when it is within one's power to do, excepting when that is the subject.
For instance, rarely do I have to tell anyone how I would wish to be treated. They will treat me exactly as they would treat someone in a long, nice garment, wearing a bespoke hat, carrying a fancy stick that is built without a rubber foot that he probably doesn't need for walking, and clearly not a hobo.
This has in my experience evoked just the right balance of respect, wariness, and fear people generally bestow on people capable of designing great things, working with the ether that is real, teaching sand how to think, and playing with the waves of the universe to see new sights and wonders as the universe may offer, and otherwise studying all of the metaphysical.
It's just most wizards were born before our first age of magic, when the truth was rare, the stakes high, and the output miniscule.
