Once again, Cofty I am not disagreeing with you that the Taliban's treatment of women should be opposed. What I am still waiting for is any objective basis for that judgement. My opposition is purely subjective, in as much as the Taliban's views are contrary to my own on matters such as whether there is a God, on how women should be treated, and the freedom individuals should have to express themselves. There is nothing objective about any of that, and we shouldn't shy away from saying so.
You say an objective morality would be based on well being, which sounds to me like a version of utilitarianism. That the greatest benefit to the most individuals is he best ethical outcome. I admire people like Peter Singer who pursue this sort of logic. But ultimately you still have the problem of defining what is good, a benefit, or well being, and how to measure conflicting interests. Absent an ultimate being there can be nothing subjective at any stage if this process.
