But that’s changing Joe’s belief about whether sharing his design is likely to cause mass murder, not changing Joe’s preference about whether he wants mass murder to happen.
But there are other stories where the preference itself changes. “If you approve of womens rights, you should approve of Gay rights”.
No, I’m saying that morality is a useless concept and that what you’re calling moral discourse is some mixture of (valid change of beliefs based on reflection and presentation of evidence) and invalid emotional manipulation based on sloppy thinking involving, among other things, undefined and undefinable terms.
Everything is a mixture of the invalid and the valid. Why throw somethin out instead of doing it better?
“If you approve of womens rights, you should approve of Gay rights”.
IMO we should have gay rights because gays want them, not because moral suasion was used successfully on people opposed to gay rights. Even if your argument above worked, I can’t envision a plausible reasoning system in which the argument is valid. Can you offer one? Otherwise, it only worked because the listener was confused, and we’re back to morality being a special case of psychology again.

Because I don’t know how to do moral arguments better. So far as I can tell, they always seems to wind up either being wrong, or not being moral arguments.

They are not going to arrive without overcoming opposition somehow.
Does that mean your “because gays/women want them” isn’t valid? Why offer it then?
Because you reject them?
