I like the word. You need to be in a position similar to mine to truly appreciate its wonderful nuance. I've never used it, and never plan on using it, to describe people who have Downs Syndrome (they're so adorable) or who are Developmentally Delayed..."retard" or "retarded" is really a great word for describing, not just stupidity, but loud, righteous, angry stupidity...like Nancy Grace or Ward Churchill.
Nope. I'm keeping this word. It's too damn useful.
