I'm not sure about this (sounds like Sam Harris).In regards to morality, which seeks the best good and least harm for everyone, to the degree that benefits and harms can be objectively measured, morality is objective.
What we consider to be a harm or benefit is a value judgement so not objective.
I've avoided reading Sam Harris due to his book on Free Will.
Harm and benefit can often be matters of scientific objectivity. For example, we can consult a biologist to get an objective evaluation of what things are likely to actually harm or benefit a given shrub.
