The Place for Morals in Society

Ok Ted, here's the deal.

I am very confused by the way the left, and you to some extent, see moral standards. Observe:

Unless this ties directly into your choice of religion which dictates your set of morals, you can't state moral standards as an absolute.  We all were raised in different places under different circumstances, and what may be moral to some of us may not be the same for others.

This is what you said to me on the CBS thread. I took this to mean that no one person, or group, or special interest can deem something an absolute moral imperative that everyone else must obey. What the left finds morally important, someone on the right might not.

That doesn't mean that I think you have no morals. To me, it means your moral standards are fine for you, but they are not the whole shabang, and they can't be forcibly applied to me, because everyone is different.

By this logic, the urge to feed the poor, while a moral standard you hold dear, might not be held by others. Feeding the poor is not necessarily a moral absolute that everyone is bound by.

In light of this, why is everyone in society expected to feed the poor as part of a collective moral imperative?
