sharing a link with you: , on use of the R-word.
I've always said that as each derogatory word gets " outlawed", the new term eventually gets a new connotation, and also gets used to stereotype and insult. The problem is the underlying attitude to those we feel are "beneath " ourselves. ..... However, as it turns out, "intellectual disability" is such a cumbersome long word, it just doesn't get used as slang or an insult, and that is definitely the way to go.
