if you really need an explanation of "Why?", MAG, here it is:

This music was profiled not out of any interest in politics, or out of any intent to present a "balanced" view of folk music, but because it is "outsider" music-also called " fringe music," "strange music", "weird music" and a number of other things. It's music that features one or more extreme elements that take it outside of the realms of what is generally acceptable, or even listenable.

Beyond that, I think that you're being really tedious about this all, and ought to just try to get over it.
