For those of you new to the blog, let me briefly sum up my meta-ethical and ethical positions.
I hold meta-ethical subjective relativism: ethical properties (i.e. good and bad, right and wrong) are not objective properties, i.e. properties of objects or other actions, conditions, or states of affairs outside the mind. They are purely subjective properties, properties of minds, and are properties describing the relationship between minds and these states of affairs.
Things are not good or bad; There is only that which we approve of or disapprove of, i.e. that which we value.
My personal set of values can be summed up accurately enough as libertarian humanism: I value human life, liberty and happiness highly, especially my own, and I disapprove of human suffering and death. I therefore also approve of people who have more or less the same values as me, and disapprove of those who hold contrary values.
I do not "hate" anyone, in the sense of wishing them death or suffering. There are people I hold in contempt, even disgust, but I do not hate them. If my contempt or disgust causes you suffering, then you have merely (!) to change your values to regain my good graces. If you don't care about my contempt, then it causes you no suffering, and I feel no guilt.
There are subtleties to this position, especially when one person's happiness depends on another's suffering, but most of the time one can apply simple libertarian humanism to correctly predict my values.
