A hundred years ago, D.W.Griffith portrayed race relations in America in a very practical, authentic manner, in Birth of a Nation (1915).  And the jews and the liberal establishment gave him hell for it.  Today they still do, but the movie was true then, and it is true now.  Have 100 years of multiculturalism and diversity been good for America?  Yes, it has been that long.  The jew "Israel Zangwill" wrote the play "The Melting Pot", the propaganda that made the term famous, in 1910, and it has been all downhill from there.
