They all have new titles.
People can no longer be deaf or retarded, they are now hearing impaired or mentally challenged.
It seems that there are more new titles in the English language then in Aisle One at Barnes and Noble. While it takes awhile to adjust to all these new titles, it can be fun and to your advantage. You won't offend anyone and you get a good chuckle at the same time. In order to be accepted these days you must master the new language. It is much like the old language except for what used to be taboo isn't and what used to not be is.
