Morality

[Pat Mustard]

In this naturalistic worldview, when you state something is good/evil, right/wrong, isn't that just pure subjective opinion that ebbs/flows with societal/cultural acceptance and personal opinion?  If so, on what basis can one judge any act as wrong/evil both in different cultures/societies or different eras without it merely being personal preference and thus have no grounding in truth.

In every worldview morality is subjective and subject to change. Christian morality has changed immeasurably since it's debut in 325CE. The difference between the naturalistic view and religious views is that we don't kid ourselves that the source of human morality is some outside, perfect and unchanging being.
