Belief is belief, by definition.
I would say that science does have this abstract view at present of no right and wrong about moral issues. But that doesn't mean that one cannot make observations about the situation that go beyond personal beliefs that have no observational backing. Science could advance and make a rational morality. I am interested at the tremendous reluctance to do this. I have never met a person who would deny their interdependence, take off their shoes and clothes and head out to prove it.
