Deconversion and some doubts

[Acrobat]

There we have it. If any kind of god, theistic, deistic, or other-than™ is required and if there’s any explanation for that, you don’t know how and you don’t possess that explanation.

So, why would you think that a person who no longer believes in a god would just stop believing in moral realism? Can you explain that?

As long as they agree to your definitions that moral statements are descriptive and not normative. That good and bad are just descriptions of harm.

Yes, an atheist can stop believing in god, recognize objective harm, which seem to be your minimum requirement for moral realism.
