My suggestion is simply to accept it. There have been many hundreds, if not thousands, of words that have changed their meanings in the last century in this country alone. It is how a language evolves.
When a person gets to a certain age, I feel it is an unheard whisper to say "I don't like how that word is being used now." One person isn't going to change it. The designers, the magazines, the book publishers, the huge multi-billion "quilting industry" has re-defined the notion of scrappy.
Quilt on. Enjoy yourself, challenge your skills, get creative. multitudes of fabrics are calling out and saying "Come play."
