And who's going to be the judge of what is moral and what isn't?

I think we already have something indisputable that gives us that answer. But if you're looking for something non-religious, try what they are teaching in public schools; The Humanist Manifestos I & II and Values Clarification.

May I say that I'm against these ideas wholeheartedly? Again, I ask; who is going to have the final authority on what is right and what isn't?
