Yes, I am asking because my suspicion is that many people who label themselves as utilitarian evaluate a situation like this one using deontology-like rules and not utility calculations and was curious if this is the case.
I'm not a deontologist either. I'm an egoist. I do use utility calculations, but I seek to maximize my own utility, not the world's.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
