All persons are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly affects all indirectly.
I can never be what I ought to be, until you are what you ought to be, and you can never be what you ought to be until I am what I ought to be.
-- Martin Luther King, Jr
This seems true at a number of levels -- inter-personally, spiritually, and, yes, racially.
