I have taken up the subjective stance that no-one is my equal.
No one person is worth my life because my life is the only one I am intimately aware of.
Now please don't take this as me being a horrible person. I love to help people and even make sacrifices of myself for them.
From this nugget of truth for myself I built up a holey moral structure, but it works for me, but to get back to the coversation.
We are all made of matter so we are equal in the sense that we are created from the same stuff. After this I give every person (even my enemy) a level of my love. I then color that love with my past experiences with that person. Or at least I think that is how my perceptions work.
So everyone is equal because I say so. heh
