I have been reading about newspeak, where people design their language's lexicon in such a way to make thought difficult for certain ideas.  Like removing all racial words to get rid of racisim, or the reverse. or rearanging a lex in a way that presumes a beleif in a diety or multiple dieties.  Has anyone done this? and if so, what parts of speech, etc is used to effect this...
