Moral Relativism

Can't we all just agree somethings are wrong and other things are right. Can't we just argue it out until the last point has been decided and compromised on.  So that we then can all agree to grow-up and work together instead of arbitrarily forcing people on opposite sides of the morality fence.  It's like the grass is greener on the other side problem, only in reverse. That a person is always wrong until they join my team, then all of a sudden there always right.  It just makes no sense, were has the value for universal truth gone.  I guess it got destroyed in the wake of everyone realizing they can't always get what they want, forcing them to revert to children.  I just think so many people need to grow-up, get over themselves, and realize there is more to life then there own selfish wants and desires.
