juanmaria,
what do you do when people start using your new word in a pejorative way?
i think we look for new words to escape from the fact that we want to express something cleanly even though we haven't really changed our ideas at all.
history is long. it's pure arrogance that makes us think we're in the driver's seat now more than any time in the past. people were as smart as us 50, 500, or 5000 years ago, and they talked about the same things.
and they invented new words, just like us. and strangely, these words haven't changed a single aspect of our characters yet. we still use them to hurt no matter how free of these associations they seemed at the time of their installation.
this doesn't mean i don't think language should change - i'm not a conservative at all. but a word is just a sound to describe something. its use is up to many more people than its inventor could dream of.
