From up close it would be easy to dismiss Less Wrong as overly confident in a suspiciously homogeneous set of philosophically questionable meta-ethical beliefs, e.g. utilitarianism.

What is giving this appearance? We have plenty of vocal commenters who are against utilitarianism, top-level posts pointing out problems in utilitarianism, and very few people actually defending utilitarianism. I really don't get it. (BTW, utilitarianism is usually considered normative ethics, not metaethics.)

Also, utility function != utilitarianism. The fact that some people get confused about this is not a particularly good (additional) reason to stop talking about utility functions.
