You might find my post about objectivism interesting. I just authored it a few hours ago, and was scrolling through and I found this.
I disagree with your reasoning, however. You said that it may or may not correlate with your existence. I think objectivity is about facts. And I personally do subscribe to black-and-white models. Clearly defined rules, lines, or morals can be used to navigate any grey area.
Once again, just my opinion.
