Given that you don't provide any actual content, but seem to spend all your time formatting articles  and reverting people, I suppose  I oughtn't expect you to understand that the vast majority of content on wikipedia starts off unsourced.  Wikipedia moves forward by sourcing unsourced material, not by removing it.  It certainly doesn't move forward by removing trivially verifiable information, like my Niger-Congo languages edit that you reverted, in which I merely added a statement that most of the languages of central, southern, and eastern Africa are Bantu.  (I apologize for the vulgar edit summary in my revert. I was irritated.  I stand by the contention made there that it was a total WP:POINT violation. )
