I think you can still have morals - I'm just saying that your morality is a product of you personally interacting with the world. There's no fountain of moral knowledge that we collectively drink from. So.. don't be surprised when your morals diverge from another person.
Oh, I think I understand what you mean. Still, I don't think we can reconcile our differences if we can't agree on and enact some morals as law. We agree that there's no objective morality we can discover, but acknowledging that doesn't solve the very real moral conflicts.
The biggest value for me is that it helped me breakdown my moral positions so I figured out what I truly cared about. I had previously held many culturally influenced moral positions which I found little to no grounding when seriously considered.
"Objective morals" are extremely religious, culty, hivemind-like because they are passed on as matter-of-fact truths that don't need to be examined, regardless of whether it comes from a region or your favorite insta influencer. They get repeated as mantras by many who cant back up their beliefs.
