retards

can i just say that i like people who are actually mentally retarded, but i hate "retards"?  i would way rather spend time with a person who is literally retarded, than with a person who is not but is commonly referred to as a retard based on his or her actions and statements.  i propose we stop using that word to describe people who actually have some kind of mental impairment, and use it only to describe people that are generally stupid for no clinical reason.  then we can call the genuine retards another name, like adult children or something along those lines.  i would like that world much better.  i don't like when i am forced to call someone a retard, because this gives actually retarded people a bad name.
