Descalzo's Journal: Right and Wrong

I feel like lately I have been apologizing for knowing right from wrong, or trying to justify it through arguing or something else. I think I need to stop doing it. How do you know something is right? I think it must come from God. Someone believes that same-sex marriage is a good thing, and should be allowed. How do they know that? What makes them so sure it is good? Is it their belief that all should have the same rights? And what makes them so sure that is correct? And so on. Where is the foundation. And when you meet someone who seems to have a different foundation than you, how do we know which person is correct?

For example, let's say that Osama bin Laden is arguing with me over who should die. He says that infidels need to die, and I say that we should let people worship how, where, and what they may. These are not compatible, and unless one of us gives in (he loosens his stance, or I convert to Islam), we are going to probably have trouble. So what can we discuss? I know bin Laden is wrong, but how do I show it? I really believe in my ideas of right and wrong. So who am I to judge bin Laden? Who am I to stop him from doing his thing?

Another thing. If there is no 'right' or 'wrong,' then do all value judgements go away?
