I once read a little book, either by or with Jerry Rubin in it. It was about how they went to Cuba and learned how to undermine our nation. One thing in particular I remember from reading it, about thirty five years ago, was that the Cubans taught them how important it was to destroy our language, as much as possible. They felt it one very effective way to undermine us. They are definitely still at it today.
Yep - you can see the attempts with the way once common words/phrases have been deemed to mean something totally else and also be criminally offensive...
