That's circular reasoning. I deny the existence of a natural right and wrong. Thus, your reasoning fails. The only right and wrong are the ones we have chosen to impose on ourselves to preserve our society, which we have determined is more important than living like animals with no rules. (Well, even animals have rules, but I think you're following me.) We have determined that cooperation in social structures is more important than "do what you feel" day.
Maybe I look into the eye of a newt, and see love there. (And no, you can't call me Gussy Fink-Nottle).
Interesting... So you admit then, do you, that your belief in god is EXACTLY the same as a small childs belief in the tooth fairy? Maybe we're getting somewhere after all. So can I take it that Osama Bin Laden would be your proposal for sainthood? after all, he made lots of people join their god, didn't he. Look mate, I'm sure you're a nice fella and all that... most religious people are... (well, kinda... except when they start killing off other people who disagree with them, which happens fairly often actually but there we are), but at some point you're going to have to admit that there is no logical way you can prove the existence of god. That's pretty much the whole point of the deal, y'know?
