Rewriting history the post-American way

One of the trademarks of post-American thinking is that America was so worthless, so racist, so evil, so bad and wrong about everything, that the world will be a happier place once it's out of the picture.  To buttress this notion, we learn that every culture, civilization, racial stock, and nation that wasn't Anglo-American was, in fact, superior in every way.

First on that little tablet was, of course, the switching of labels that occurred with the colonists, settlers, and Native Americans.  In this, we learned that there were indeed bloodthirsty savages, brutal barbaric murderers who couldn't be trusted, whose only meat and drink were lies and lust for carnage, and whose demise any person of a true heart must obviously desire.  Naturally, there were the heroes, the pure and honest champions of virtue, tolerance, love, and honesty opposing these subhuman creatures of the night.  Same basic story, we just switched the name tags around.  Now we know it was really the European settlers all the time who were liars, thieves, murderers, savages, environment haters, and religious types.  The Indians were, in fact, as close to perfection as one can ever get (really, have you ever heard a representative of an American Indian tribe say that tribe was wrong or to blame for anything?). 

Now, we have the next edition of this trend.  For we find that not just the American Indians, but in fact all non-Anglo Americans were superior, and have a tale to tell.  In this little PBS story (a major proponent of the post-American curriculum), we learn that Billy the Kid was actually quite the hero to Mexicans of the day.  Sure, he killed and robbed.  But mostly he did that against the Whiteskins, so no harm, no foul.  He promoted a sort of anti-American anarchy, seemed  to be pretty loose when it came to morals, and was actually a major defense against the White Racist Americans (TM) of the day.  What could be more praise worthy?
Oddly, many in the comments section smell a rat with this one, and if folks who frequent such articles to comment can smell it, there's always hope that others, when confronted with such obviously propaganda based rewriting of the past, can as well.  Not to say there isn't always the chance to learn from new information, or even see things of the past in a new light.  But the post-American, post-modern hermeneutic is so predictable, so conformist, and so narrow one can't help but be suspicious as every shred and scrap of history seems to fall into this 'new' mold and prism through which all facts must be read.
