Can I just say that this is an awesome topic? I have been thinking a lot about this for several weeks. A certain event started the wheels in my mind, but there's one word we all need to learn from the inside out. Acceptance! I agree with all your points and I think my word is incorporated into what you've said, but you asked what would we add.  I would add - Accept the differences. Hopefully as I accept differences in others, they will accept the differences in me. It's not a balanced world. As any scientist, even the Earth is tipped on it's axis. If you want one more word - tolerate while growing in acceptance.
