No, it has already been pointed pout to you that there is not objective moral truth. You need to read more history and social sciences; what can be of potential hazard is exactly the opposite of what you’re proposing. It’s the search for “objective moral truths”, that obviously isn’t there, that can lead to gross misunderstandings (stoning the gays, the superiority of the Arian race, Lysenko’s ideas about crops etc.). When you base your moral ideas about something that’s not true, you are bound to go wrong until reality forces you back on track. That’s the lesson learned form history, and that’s why modern secular societies seem to be better off than current Islamistic or deeply theistic ones (or Nazi Germany in the past). Realizing that we humans are responsible for our own action (not to an illusiory being or to dreamed-up “objective” ideals, but to our selves and our fellow creatures) is the only sensible position.
You are, in effect, proposing something that has the potential to become a new dark age – an then it’s up for the lucid people who can see trough that social madness of “objective morality” that has to set things back on track, again and again. Only because some theistic-oriented people find it intolerable to not dream-up some “objective moral truth” is not a reason for other people to adopt the same kind of psychosis. You simply have to deal with the world as it is, you simply have to grow up.
