See, you are applying too narrow of a definition to the words if you are so offended. One meaning of retarded is someone who's mental acuity is lower than a particular threshold. There are other understood meanings in conversational English. One is a situation that is just dumb. This definition is separate than the other. An engine can have it's timing retarded, yet no one is accusing the engine of being mentally handicapped.
The same goes with gay. One definition of gay is someone who is sexually attracted to members of their same sex. Another definition is someone who is happy. Sill, another understood definition is a situation that is strange or different. All of these definitions are mutually exclusive.
When someone is accused of being, dressing like, or acting like a ho they are not being compared with a tool that is used to loosen clumped dirt. The word is used in a different context because it has different definitions in conversational (aka slang) dialogue.
No word offends me, not a single one. Not one used in front of me or even directed at me. Words are just collections of letters, I don't attach emotional value to them.
As the parent of a daughter with Mental Retardation, I find your viewpoint very insulting.
The fact that you even admit that using the word "retarded" is to use it to describe something "dumb" shows how ignorant that viewpoint is to the population that are clinically retarded.
You are using a medical term to describe their developmental delay to refer to an act by a person that is "dumb". Can you not see that this is a direct slam to anybody with mental retardation in that if somebody is "retarded" or acting "retarded", it is negative and "dumb."
To use somebody's medical condition to describe an action as "dumb" in a negative connotation is very insulting to the group.
My daughter has Down syndrome. Words don't usually bother me, I have a pretty thick skin when it comes to politically incorrect use of language. For instance, I have had people ask me if she is a Mongoloid or is she a retard, both considered politically incorrect and highly insulting. However, that doesn't bother me because they were or are clinical terms for her condition.
However, to use Retard in an extremely negative way to denote poor behavior of somebody not mentally retarded is an insult to my daughter and thus, insults me.
To try to say it is "ok" and those of us with loved ones with developmental delays should just accept it, is even more of an insult as it implies that my daughter would not understand that others are being characterized as a "retard" because they are doing stupid behaviors.
My daughter is not stupid or dumb and her mental condition should never be used in a demeaning way to describe other people's stupid and dumb behavior.
