Politicians and government bureaucrats are oblivious as to what their intended functions are. Like in George Orwell's "1984," they think that, by manipulating language, they can control our thoughts. Now the Library of Congress has decreed (I suspect with some direction from above) that the terms "illegal alien" and "alien" are now verboten ... see: Breitbart Article. As a lover of words, I can't say how offensive it is to see our servants again trying to be our masters by suborning our language.
