There's no morality without an opinion. Therefore there is no completely objective morality.

Morality only has meaning within a context, which must be at least personal, and perhaps also must be social.

Only with a point of view agreed upon - a religious, moral, or personal code that is consistent, is it possible to give moral judgements. Even then, they are only valid in the context of that point of view.

...

Of course, above that philisophical point, there is wide ocean of practical and applied morality, which involves multiple cultural elements and personalities, and is perhaps the broadest landscape of grey ever. Moreover, that's where morality is actually used, and to good effect.

So, some statements can be entirely morally true FOR SOME AUDIENCE, and especially so for an individual. However, it's never going to be true for everyone, unless you kill everyone who disagrees with you - welcome to Crusades, Inquisition, Jihad, and the "Wars"(tm) on Drugs and Terrorism, Intellectual Property, privacy, abortion, etc.

The better option to trying and failing to kill everyone who disagrees with you (which never works, because people tend to hate killers), is to create an isolated community. Or, to alter your morality in a way that lets you get along people who disagree with your moral code.
