My point of view:
No cultured person would ever say such and such is a language of uncultured. There is no uncultured language on earth. It will only be associated to ugly and dirty words of sex. Any language is an intelligent creation by wise and learned people and in course developments of history. One who knows a language would not call it ever an uncultured languge. During the last century only snobs, snoopys and uppish aristocrats defined something out of vanity and big-headedness certain languages as low grade and below there dignity. In history there were always such foolish people, during Napolien era, for example. It was the same in Music world for many decades. In modern times the african music particularly in America is being adored.
