I could be okay or not okay with anything, depending on the circumstances. Rape, murder, genocide, whatever. I think perhaps that the thing I disapprove of most consistently is dishonesty. Especially intellectual dishonesty.

Because I tend to dislike intellectual dishonesty, I don't harbor the pretension that my disapproval is a product of some sort of Platonic moral law carved into the fabric of the universe. No, I know full well that disapproval and all other moral feelings are just that, feelings, no more enlightened or truthful than anger or sadness or sexual urges. There is no more objectivity to an action's wrongness than there is to a person's sexiness. It's all just preference.
