As far as I'm concerned, the way I phrased equality was related to judgement.
I can totally accept we are not equal. We are worth as much as our acts and as much as others value them. It's a multi-dimensional parameter, of course, one that can not really be described with 90+% of confidence.
Anyways, for me, a healthy community, even large-scale has one very important "benchmark": equality under the law. Had I committed a crime, I get the same level of penalty as someone else who has done the same. No exceptions. Period.
Morally speaking, our differences should not influence what are we "allowed" to do with other people.
Of course, its problematic part is the nature of law. No matter how hard we try, laws are never fully objective, and even then can be exploited or modified to be exploitable. And of course, ther would never be complete consensus on law.
But then again, it's way too problematic to give people, "simple human being", no matter how smart they are, such an enormous privilege, especially when it comes to decide about life and death.
It's just the best we could do - yet.
