Summary of this thread from my perspective:
A: I want you to do x.
E: No, I don’t do x for anyone.
A: But I want you to do x for me. It’s rude if you don’t.
E: It’s not rude, it’s neutral. And like I said, I don’t do x for anyone. There’s no reason I should make an exception for you.
A: I told you it’s rude. You should change your ways and do x for me. It’s the right thing to do. (Aside… I don’t even actually care if E does x, I just want to make a point)
E: Why do you think it’s the right thing? If I do x for you, but not others, then I’m being inconsistent with my principles and beliefs. Here are the reasons I don’t do x for anyone: (lists reasons).
A: I told you it’s rude, and you’re an ass if you don’t do x for me. It’s just a polite request, why won’t you do x for me when I ask you to?
E: That doesn’t sound like a polite request, it sounds like a demand under threat of social condemnation.
A: It’s not a demand. I just want you to change your ways so that I’ll be happier. It’s the right thing to do.
E: I disagree, and I don’t see any good argument for why your particular view on morality is one I should adopt. I don’t adopt the moral beliefs of other people on request, no matter how strongly they believe they’re righteous. Why do you think you’re important enough for me to make an exception to my principles?
A: Because I told you I’m right and I asked you to.
E: Would you set aside your deeply held principles at my request?
A: No, because you’re wrong and I’m right. I want you to do x, I asked you to do x. If you don’t do x you’re rude and an ass.
E: That’s not a compelling argument. I take a neutral approach that never contradicts anyone’s belief on this topic. I’m not going to change that just because you want me to, it’s something I deeply believe in and am committed to. I’ve been doing this consistently for a very long time.
A: But I told you it’s rude! I want you to do x for me!
E: No.
A: [rant, expletives, insults]
E: You’re being uncivil, disrespectful, and rude.
A: [flounces]
