Is it true that there is no absolute morality?

[bennyboy]

The ideas are not the essence of morality, rather they are the subjective expression OF morality.

This is just playing with words.  Morals are a product of brain activity so yes the ideas are the essence of it.

My point is that while specific moral ideas are mediated by personal and cultural differences, the tendency to formulate and act on moral ideas is intrinsic to the species.  It is so predominant that it represents an objective reality, no less than humans having 10 fingers and toes and so on.
