Other: There is only one right morality criteria, but it is not written into the fabric of the universe or anything. It is the idealized criteria that humans refer to as "right". It is not relative to belief or individual preferences.

What I care about (my utility function) includes this abstract morality, but also very relative things like "I like human females" and "I'm more important than you".

I'd say accept moral antirealism except that that is too easily construed as relativism or some other philosophy.
