I know it's been some time, but I wanted to thank you for the reply. I've thought considerably, and I still feel that I'm right. I'm going to try to explain again.

Sure, we all have our own utility functions. Now, if you're trying to maximize utility for everyone, that's no easy task, and you'll end up with a relatively small amount of utility.

Would you condone someone for forcing someone else to try chocolate, if that person believed it tasted bad, but loved it as soon as they tried it? If someone mentally deranged set themselves on fire and asked you not to save them, would you? If someone is refusing cancer treatment because "Science is evil", I at least would force the treatment on them. Would you force transhumanity on everyone who refused it, is probably a better question for LessWrong. I feel that, though I may violate others' utility functions, we're all mentally deranged, and so someone should save us. Someone should violate our utility preferences to change them. Because that would bring an enormous amount of utility.

I'm struggling how to reconcile respecting preferences with how much of society today works. Personally, I don't think anyone should ever violate my utility preferences. But can you deny that there are people you think should have theirs changed? I'm inclined to think that a large part of this community is.
