And then the actual definition is "slow" or "to slow".
Fire retardant
Tardy for school
Mentally retarded
The word doesn't bother me in the least.
MOCKERY bothers me. Insults bother me. But specific words? Not so much. ANY word can be made insulting. Genius is a favorite insult of my own.
I'm ADHD-c. People OFTEN use that word to describe being an idiot. Doesn't bug me. My cousin is an extremely low functioning autistic. Doesn't bug any of us when people use the word retarded. UNLESS its being used as an insult "Hey! Retard! Guh! Guh! Guh!"
Course, "Hey supermodel! Guh! Guh! Guh!" is equally offensive
Do I use it around people I know it offends? Nope. Nor 'moist'. Nor 'crazy'. (I had someone JUMP down my throat a while ago because of 1 of my 2 favorite people watching games is "Crazy or Cellphone?". She went in at length that if I had any experience or compassion for mental illness I would never use the word crazy because it's offensive to schizophrenics (which is no longer a current term, although she didn't know that). Honey. I've got mental illness in my life in spades. Crazy is not 'mentally ill' except in the broadest most outdated sense. Heck, I talk to myself/inanimate objects/etc all the time. And furthermore, FAR more people than people with schizoaffective disorders talk to themselves. Shall we break out the DSMV? I can think of at least 9 disorders, and a huge number of diseases, and even more illnesses where talking to yourself is in the symtomology.
To be honest, in a world where we are getting extremely precise, general terms used in ignorance bother me far more. Like crazy does NOT equal mentally ill which does NOT equal most disorders. ADHD, just for example is not mental sickness. Neither is low intelligence. And 'retarded' falls into that spectrum with me: having as lite to do with most intelligence/ neuro issues as crazy does with mental illness.
