I imagine that gulf of perception is what actually needs to be crossed somehow in the debate between hardcore utilitarians and those of us who are not.

But "these conclusions" are unobjectionable, because they include the premise "things are net better". Because "net better" is imprecisely defined, I can substitute as strong a condition as desired up to and including impossible conditions. Which means they can subsume non-utilitarian moralities (I believe non-utilitarians are just utilitarians with binary step functions for certain utilities).

Again, see "The Ones Who Walk Away From Omelas." I hope I would walk away, even at the price of slow starvation.

I believe I would, but it is hard to know what you will actually do in a truly awful situation before it arrives.

Because to you, Omelas is not net better. Which is perfectly understandable. But what basis do you have for rejecting Omelas, other than that you believe it to be worse?

It's not about utility, it's that it's wrong to hate and harm a few people. The "good" of the many does not have one iota of influence over the wrongness of that action.

To quote the book that defines so much of my moral code, "What does it profit a man if he gain the whole world but loses his soul?"

Side note: describing my worldview with language from yours does not mean yours subsumes mine.
