Manholes became personholes, chairman or chairmen became chairperson or chaipersons (which is fucked because people is the plural to person), handicapped became disabled which became diffable (sounds like a fucking lisp), nigger and black became Afro-American (what about the abos here - they weren't from Africa and they DEFINITELY aren't from America), and dwarves became 'little people'. Jesus Suffering Fuck, get me the fuck away from these morons.
Leave the fucking language alone.
