according to dr. king, what does segregation do to the segregator and to segregated?

Any law that uplifts human personality is just. Any law that degrades human personality is unjust. All segregation statutes are unjust because segregation distorts the soul and damages the personality. It gives the segregator a false sense of superiority and the segregated a false sense of inferiority. To use the words of Martin Buber, the great Jewish philosopher, segregation substitutes an “I-it” relationship for an “I-thou” relationship, and ends up relegating persons to the status of things. So segregation is not only politically, economically, and sociologically unsound, but it is morally wrong and sinful. Paul Tillich has said that sin is separation.
