Personally I admire the National Association for the Advancement of Colored People's hold onto it's title. I think that this show a commitment to real change and not to a superficial change that a change in term often is.
In the UK the Spastic Society held onto it's name for a very long time and thus put the word Spastic onto charity shop fronts and through letter boxes, which I felt was a good thing in that it would have changed attitudes to cerebral palsy and physical disability general over a long period. However, they have, for some reason, changed their name to the meaningless SCOPE in the last few years.
