Direct and Indirect Realism ASSUME there is an external world out there that is mind-independent to the extent, even if there are no humans, whatever is out there still exist.Indirect realism seems to have thrown a veil of perception over our eyes, saying we can never perceive the world as it truly is.
If this is the case how can we ever know for sure that what we are perceiving is what is actually out there and,
Even further how can we be sure there is in fact an external world beyond that veil if we only perceive the sense data.
We never come in direct contact with the external world, how can we be sure that there exists such a thing.
Ultimately it is just our ideas that we perceive the projections on our minds.
Why then should we assume there is a physical world that is creating the ideas rather than take the approach that reality is just a set of mental ideas with no external world.

The conception of a mind-independent physical world out there is driven by a natural evolutionary default emerged to facilitate basic survival.
The problem as related to Morality is Philosophical Realists [PH & Gang] cling to it dogmatically as an ideology which is uncompromizable.
As an ideology of philosophical realism, the mind-independent reality that is deemed to be very real by p-realists is actually an illusion and it is delusional of them in insisting upon it dogmatically.
The issue of morality, is p-realists grounds on an illusion to deny there are objective moral facts.

To p-realists, moral elements are based on rightness and wrongness which are mere opinions, beliefs and judgments which are subjective to humans and thus cannot exist as mind-independent facts, i.e. p-realists' version of illusory facts.
The p-realists sense of mind-independent fact is illusory.
Why Philosophical Realism is Illusory

Because the p-realists' ground is illusory, p-realists has no credibility in claiming there are no objective fact and that morality cannot be objective.
On the other hand there are real facts [FSK-ed] that are conditioned upon a human-based FSK of which the scientific FSK is the most reliable.
Scientific facts that are moral elements when inputted into a credible moral FSK will enable objective moral facts, on that basis, human-based morality is objective.
The human-based scientific FSK deals with the empirically external world.
Because it is human-based, it follows deductively, its resultant reality cannot be absolutely human-body-brain-mind-independent [countering philosophical realism mind-independence].
