For many decades the legal name for people with learning disabilities has been mental retardation.  However, because of the slanderous way a portion of this term has been used, many people are no longer using it.  Even the highest offices in our country have been guilty of using a word from this term as a slur to show contempt or derision. 

Respected blogs were tagged with this label until recently.  However, I realized the other day that all of the professional blogs with this tag have disappeared, except this one.  I would never want to be offensive, yet I wonder if there is still a need to use the legal terminology?  What do you think?
