I do not like the word "morality". It is very ambiguously defined. The only version of morality that I even remotely agree with is consequentialism/utilitarianism. I can't find compelling arguments for why other people should think this way though, and I think morality ultimately comes down to people arguing about their different terminal values, which is always pointless.
morality ultimately comes down to people arguing about their different terminal values, which is always pointless.
Arguing about them may not be fruitful, but exposing truly terminal values tends to be illuminating even to the person instinctively and implicitly holding certain values as terminal.
Do you believe in an objective morality capable of being scientifically investigated (a la Sam Harris *or others*), or are you a moral nihilist/relativist? There seems to be some division on this point. I would have thought Less Wrong to be well in the former camp.
Edit: There seems to be some confusion - when I say "an objective morality capable of being scientifically investigated (a la Sam Harris *or others*)" - I do NOT mean something like a "one true, universal, metaphysical morality for all mind-designs" like the Socratic/Platonic Form of Good or any such nonsense. I just mean something in reality that's mind-independent - in the sense that it is hard-wired, e.g. by evolution, and thus independent/prior to any later knowledge or cognitive content - and thus can be investigated scientifically. It is a definite "is" from which we can make true "ought" statements relative to that "is". See drethelin's comment and my analysis of Clippy.
