Whether morality is or isn't binary isn't quite the point you should be making. It's that not everyone shares the same views of morality. Some people find private property immoral, for instance. The reason that we have moral "gray" areas isn't so much because morality isn't binary, but more because what different people view of as moral varies. In a purely utilitarian sense, non-binary morality is more concerned with how closely an action comes to the "greatest good" in that an action can be morally good but not morally greatest good. But what defines the greatest good depends on how person defines morality.
